A friend was having trouble with there bass boat not getting up on plane. They took it to several different shops and no one could fix the problem. Finely someone mess with the prop vents and that was the fix. I recently told Frank about your youtube channel and how you helped me with a 2 stroke problem I was having a few years back. And you were the only one that knew what you were talking about. And how you emailed me back and forth and fixed my problem .I told Frank to check out all your videos and there may be one on his boat problem even if you solved it. Keep the videos coming I've watched them all. Thank you for all your boat smarts with we could have a few beers some day if you ever come to northern California please be my gest .

I'm still lucky compared to people living in the a desert area or far from water. I have a 3 minute drive to Lake Pontchartrain and a 30 minute drive to the marshes of Gulf of Mexico for some of the best fishing in the world! Louisiana has great fishing as I'm sure Dangar Island does too. Looking forward to the video!

Chimed in on a the video about relays, fixed that issue and now I am getting some venilation issues. Always know I am gonna learn something when the blackboard is in the background. I blew the motor and bought an identical used one with no prop, bought a super cheap one to get on the water and now I have ventilation issues. Motors mounted in the same spot, cheap prop and cheap hydrofoil are the only new variables to the set up. The hydrofoil has 2 tention screws that hold the hydrofoil to the anti venitlation plate and they stick out pretty far, i would assume they could put a trail of bubbles when underway. Who knows, all I know is there is always something!

Did the boat have a problem before you added the hydrofoil? If it did they can really help, but if it didn't they can make a boat much worse.

@@DangarMarine I always had one on the one that failed but it was attached by holes i drilled thru the vent plate and bolts. Never had an issue. This new motor came with one but it wasn't installed as the motor was on a pallet but its more of a "clip on" style. Slides over the vent plate and then has two fasterner styler bolts that put tention on the vent plate but no holes. I am going to take it off and change the zink to the flate style instead of the skeg lookin like one that hangs from the vent plate.

Great video! Thank you so much. I bought my neighbors boat last summer. A 17ft. Crestliner with a 115hp Evenrude motor. When I go in reverse I have to do at least 3k rpm just to get it to start moving. When going forward it will plane at about 3k rpm but it takes up to 4500 rpm to get any more speed. When it does take off at around 5k rpm it takes off like a bat out of hell and so do the rpm's. I have to throttle back so I don't loose control. I figure it's got to be the pitch of the prop. I welcome any input on this issue.

I trimmed almost highest as possible to reach maximum speed (checked before all levels and reach max speed when trimmed all the way up) tomorrow will trim down and will try some hard turns.i tried to buy jack plate to place engine lower on transom but because it is with tiller bit difficult , i have an another option to buy extra long lower unit (can get 7 cm ) but it is quite expensive solution almost 800 usd

I'm was running a 11 1/8" X 13G on my '86' Skeeter Strada f80 w/ my 1985 Yamaha 40 HP, and I had a hard time locating THAT prop. It looks identical to the aluminum one you are holding. I did find a 11 1/2" X 13G and I figure if anything, it's an improvement w/ no harm done. I never thought searching for a prop would be so tough. I had to change out he old one due to dings and nicks from the previous owner.

I hit some debris once and torn up my prop. I bought a rebuilt prop from the local marina for half the price of a new one. Took the boat out and it was fine at slow speeds; when I'd give it the beans and try to get on plane the engine would break free like it popped out of gear. Assuming the recon prop was good, I was convinced I had broken something else. It took me three weekends to find that it was the hub slipping on the prop; it couldn't hold under higher RPMs. The recon prop obviously had gotten "spun" and the marina didn't change the hub during recon. Got a refund, bought a new one, and lesson learned.
@stanpatterson5033
@stanpatterson5033 6 жыл бұрын
Ha.... not to get off topic here, but my wife learned not to give me the beans or there'd be a lot of something breaking freely. As for the prop... was it that rubber-surround sort of mount like Stu showed in the video? Good to hear that they took it back and refunded your purchase.
@JasonThaine
@JasonThaine 6 жыл бұрын
Yes, it was the rubber pressed in type of hub. Once it gets spun free one time, it's done for and needs to have a new hub pressed in. Easier to just buy a new prop if that happens.
@stanpatterson5033
@stanpatterson5033 6 жыл бұрын
I agree, especially after just having bought it.... might be a little different if you'd had it for ten years or more before it happened.... There are a few comments around to the effect that driving screws or nails into the rubber puts forces against the spline and the outer ring blah blah blah... but again, since you had just bought the thing, I think it was best handled by taking it straight back where you got it. Kind of a shame that that particular weakness is built into the design, where a material will eventually begin to harden and then lose its bond to a mating surface. Wonder why they continue to make them that way, other than being able to sell more replacements....

I'm not sure if it is built in redundancy as such, because I've certainly got many, many years out of a rubber bushed prop. I can also see that they are more user friend to your average boater as you don't need to do anything if you hit the prop on something, just keep going provided it didn't fracture a blade or something serious. On the other hand, I really like the idea of being able to repair the old shear pin design but that might just be me. :)

Hi I live in Suirname and we have some small motors pushing heavy loads like a excavator getting pushed on a 40hp outboard!

Great explanation of the different types of props. Could you do one on whether its worthwhile fitting a hydrofoil? I have a 4 stroke 40hp on a 4.4m barra boat. Thanks, Andy.

Ah, you didn't watch to the end, did you? ;) Yep, that is one of the next things I'm going to be experimenting with on the Green Machine.

My prop started to slip this summer, I hammered in and countersunk some nails, equally spaced into the rubber grommet, parallel to the output shaft and the prop has not slipped since. Start with 3 or 4 nails and add more if needed.

It certainly can stop a prop slipping. I think with larger high performance motors the issue of being out of balance comes into play. Also be careful that you don't get stuck out in the middle of nowhere if you hit a rock or something as the nails will fail completely. Good for your gearbox, not so good for getting home!

Great video Stu. For years I was confusing cavitation with ventilation...😅. Can't wait to see the Dangar Island tour. Looks like such a gorgeous part of the world. Also interested in the assessment of those hydrofoils. I've tended to think of them as the snake oil of the boat world. If the outboard manufacturers thought a bigger anti-ventilation plate was required...wouldn't they just make them bigger from the outset? I also have heard they are supposed to get you up on plane faster. And finally...I have a question about winding the cable on a steering drum I just purchased from your sponsor (awesome price, even shipped to Canada!). The long winded explanation I've attached to the comment section of that vid you did last year on the same topic.

Thanks mate, glad the video helped you. I'm off to film the hydrofoil plate video this morning so we'll say how it goes. I think they are of more use if the boat has a problem that needs solving, which the Green Machine doesn't, so it might not be a test of their full usefulness, but we'll see.

Thanks for this critical information; explained as basically as possible. Much appreciated brother, but I do have a favor if you wouldn’t mind looking at one of my videos and telling me if the carb set up is correct. *I won’t make a habit of it!* I’ll upload it now and see if you don’t mind taking a look sir!
