I purchased a 15 HP Johnson in 1982 in Manaus Brazil to use in upper reaches of Amazon tributaries. It was a factory modified motor based on the 10 (9.9)HP motor with the stouter lower unit from the 25hp model. It had a heavy duty low pitch propeller. The advantage was that it was light weight enough to haul it up some of those 50 ft high river banks. We mounted it in a 21ft aluminum boat and travelled 10 days for our first trip to an Indian village. We put on several thousand miles of travel with that boat and motor before it was stolen. But it was a good reliable motor - not fast, but it pushed a load of 1100 kilos easily. We often had to jump over logs, and under logs to get upstream. Thanks for bringing back a fond memory!

Stephen C Foster park near me has a 10 horse limit on boat motors so everybody used to buy 15 horse and order a 9.9 cover to conceal their deception. The Rangers wouldn't look too hard back then if you weren't causing trouble. The first 2 digits of the vin plate is usually either 9.8, 9.9, 10 or 15, and you can change the 15 to 9.8 if you're careful and smudge the whole plate a little. Just a little outlaw fun from back in the day.

That water tube grommet that you said doesn't look right is just a different style that was used on those outboards especially, to make it easier to get the copper tube guided into the grommet...it is a wide mouth grommet and will work on most any Johnson Evinrude. I use them when I can...they help prevent the grommet from folding over and obstructing flow as it is nearly impossible to see if you have the tube IN the grommet when sliding the unit up into place on some motors. Great, no nonsense, helpful video for folks doing this for the first time.

Mike I was a master tech on OMC AND Johnson/ Evinrude outboards back in the 70s thru the late 90s. You are correct on the conversion from 9.9 to 15 hp. I you check the parts manual for your model year you will find that there is a shim that is fitted under the reed plate that will allow the reeds to open a bit further which in turn allows for the extra fuel. Also the difference in carburetors is the size of the venturi.

I just bought my first boat, a 14 foot that came with a free 1994 9.9 Evinrude 2stroke. Guy said it had very very low hours but didn’t run. I had to fix a couple wires that were chewed from mice. The air box was packed with acorns, and the carburetor was thoroughly cooped up. I took it all apart, cleaned the carburetor,got the Jets passing air, put it all back together and it fired up on the first pull, purrs like a kitten. My one concern, it seems to not squirt the fresh water at idle but does very well when throttled up slightly🤨 I hope it’s not a problem. I’ve only ran the motor 2 times for a few minutes so far, haven’t taken it out yet. Your video would’ve help me a lot if I saw it before I did all the work 😂

Thanks for your video. My 13yo son just bought a 1977 Johnson 15HP. It has low compression in both cylinders (65 PSI) and no spark. We are pulling it apart and trying to get it going. Tested with a voltmeter and found good charge to power pack and nothing beyond. So ordering a new powerpack. Next we took the head off - the head gasket looked OK but we found the thermostat was rusted. Piston rings look OK too. So not sure why compressions is so low in both cylinders. Anyway - really enjoyed your video thanks.

Hi. As long as I can remember the 9.9 Hp and the 15 Hp were the same engines with the 15 just boosted (sorry I was early). In my book at first look this 88 is still a beauty .Being that old the main problem will be the rubber parts craking. These were the last years of the best quality engines and Envinrude-Jonhson ruled the water for their no nonesense Chevy style. Good luck

@kypackerfan4-12-15 4 жыл бұрын

Our '62 OMC Gale 15 HP is the same motor. Split the lower unit after draining. The O ring seals in your prop shaft are probably long deteriorated to nothing, replace them. OMC did not use RTV Blue when they made these in the 60's but if the motor lower unit has hit any rocks and stumps at speed, in it's life, the rubber gear case seal could be leaking also. Put RTV Blue under the seal as well a small bead on top of it to insure it's water and oil tight. Back then OMC used fiber gaskets on the gear case filler/drain screws; mid 70's changed to thicker rubber ones. Any oil resistant gasket material or rubber washer will work; add RTV Blue to insure seal and to keep the screws from coming loose from vibration. Let the RTV Blue dry 2-3 hours before refilling with gear oil, unless temps are over 80° F, 1 hour is long enough. Low speed carb adjustment needs to come out 1/4- 1/2 turn or the jet is clogged or just worn out after so many years. Try opening 1/8 turn at a time. If that doesn't help check/add/change the fuel line filter and the low speed jet.

A top end performance tip: scratch marks where the ramp is currently assembled, loosen ramp screw(s) and tap the ramp a tiny bit (1/64" at a time) and advance the ramp into the roller. Test after each movement to be sure you didn't over advance. This also needs to be done when the roller and ramp shows signs of long term use wear reducing the originally designed advance.

As for the rubber pull handle, depending on the model year, some used a 3/16" - 1/4" flat washer just under the knot others used a small galvanized steel plate with a hole (about .3" x 1") under the knot to prevent the starter rope from pulling thru depending on the rope size/ motor HP.

I also bought a 9.9HP motor only to find out, much to my delight, that I had a 15HP motor. Many owners found out that taxes were higher for 15HP motors than for 9.9HP motors so cover swaps occurred. The covers were an identical fit for either motor. Cheap swap.

@kypackerfan4-12-15 4 жыл бұрын

They also did that because some lakes have a 9.9-10 HP limit on them (15HP on the down low); they just had to hope the person inspecting the boats and motors didn't know the model year and HP are part of the SN on every OMC outboard.

I wonder if anyone has done the conversion for that motor and if its the same parts to change (carburetor and reed plate spacers).

A 9.9 is a 9.9 because some lakes and operator ages are limited to "below 10 hp." Often a 15 has the 9.9 cover on it. And yes, a 9.9 and a 15 are usually identical engines as you explained. That is a nice little outboard.

True... Most of the 9.9's I know of are a 15hp with a smaller carburetor to restrict the power down to 9.9... Oldest trick in the book is to get a 15 carb off one with a junked bottom end.

You will find the 9.9 and 15HP are identical in all areas except the 9.9 carby is a detuned 15HP, they do this by adding a sleeve in the venturi tube and changing the jet sizes, kits are available for this purpose maintly aftermarket suppliers, but this is also common with the Mercury 7 and 10HP as well as afew other motors...

Good day, a correction should be made about proper mounting height of the outboard. The anti-ventilation plate {the wider wing on each side of the gearcase}, should end up between flush with the center bottom of the hull and up to 1.5" inches below it. If it is mounted any lower it will act like a hook and create drag, or if mounted higher the prop will over ventilate and you may end up with less water being sucked up by the water pump. This rule may be different with boats set up for racing, but they also different or modified parts to achieve the desired result.

You can fix that horrible crack in your floor very easily - get a roll of foam backer rod that will fit and some self-leveling caulk at your local masonry or big box lumber yard. Push the foam into the crack - can use a couple of rows on bigger cracks - and then fill with self-leveling caulk. It will sometime form a big bubble but just pop it when it does and it will level itself out. This is what we do in commercial construction jobs when we have this problem. If you want a concrete finish, then use self-leveling concrete. You can use it instead of the caulk or over the top of the caulk by leaving it down a little bit below the service, a half-inch should do.

I just got one of these same motors from a guy that used it very often for years. I opened it up to clean out the carb and the same exact screw was missing off the air intake and I found it in the same spot as yours. Im wondering if its not bad workmanship and just a rattled out screw.

I wish it was as simple as that nowadays... I have a 15hp 4 stroke Suzuki. Identical to the 20hp except they put a restrictor plate behind the intake, and the timing is different. Only way to step it up is to change the computer

From a marine technician to you having worked in the industry for 26 years 10 of them for an OMC dealer there’s no way that’s not the original impeller and whatever parts they gave this aren’t from this motor. impeller wasn’t melted but the rubber was laid over like it been that way forever ,and the keyway was stuck.

I replaced fuel pump and recoil spring good gas. Still wouldn't start. Checked my gap and it was set at 28000 regapped to what you said 40000 still didn't even try to start. Went and bought new plugs Ql77jc4'. Checked gap and it was preset at 25000. Put the new plugs in and guess what ? Never ever heard it run so good. Checked online and 30000 is on the chart for this motor. Not sure what up just glad to finally getting it running. Was a nice video though.

Converting a 9.9 OMC to a 15hp but keeping the 9.9 cowl was fairly common in New Jersey where many fresh water lakes are legally limited to 10 hp. At some point the newer 9.9 motors were changed and unable to just change carb to convert to 15 hp.

There is a flip lever under the gear shit that controls the tilt lock.You flip it to the position you want then pull up on the motor then relax and pull up again. It should come right up.

On these motors under power head there is a rubber grommet on copper water pipe from water pump. Many swell closed in salt water. Motors would overheat. Clean around grommet and put anti corrosion grease on aluminium. Did dozens at dealership 7.5-15 same motors. Good motors
