In this video I go through setting up the ignition timing on a Tohatsu 115HP two stroke outboard. This involves setting the idle and high-speed ignition stops as well as the throttle stops as per the Tohatsu service manual.

Stu, you are the most comprehensive resource for boat maintenance on the internet. I've been going back through some of your older videos to familiarize myself for a 17' project boat that I am in the middle of. Also, I like to comment because I know it helps your channel's statistics. I'm still following your new stuff too. Keep on digging, you've got Renko looking good.

Such a scruffy guy... such amazing explanations :) . Thanks so much! From experience, most mechanics I've used just go with the "close enough" approach when tuning rather than actually going with the actual tolerances set by the manufacturer. This is how to do the job properly.

Excellent teacher you are. I have a 2 stroke Yamaha 25 hp with 2 carbs 2008. I bought it new. At idle speed I couldn't get the pop out of it. After watching you on utube I adjusted the carbs in sync, and replaced lower unit leaking seals. Also with your instructions I got the pull rope working on a 9.8 Merc., and if I would have used your water pump drill test I wouldn't have changed the water pump. It was fine. The engine has a warped aluminum plate ,and 2 bad gaskets on the power head which turns the water to steam. I cleared the copper tube, and the rubber lines to the pisser. Parts are on order. Hope to have the motor running next week. Low,low hours on this motor which is worth fixing.

What the great explanation of timing adjustment. I assume that on simpler older engines with mechanical linkages the advance is kind of fixed by the shape of the the curved ignition plate and the roller riding between marks for the limits of advance and connected to the throttle arm for rpms adjustment. Since the connecting rods are often bent heavy wires this by itself easy the adjustment of the rest of the low and high rpms

An observation: the timing linkage socket was above the ball instead of on it, maybe this was part of the problem, IE causing binding. Also, I worked on an old 1977 140HP Evinrude V4 where the tubing over the timing stator wires had hardened and cracked. This was preventing proper movement of the stator and was flexing the wires all in one spot stressing and breaking them. Some new wire soldered in and new heat shrink tubing fixed it right up.

@DangarMarine 7 жыл бұрын

Well spotted on the linkage. This outboard has a lean misfire so I'm going to be going through the carbs soon and then we'll know the true situation with the timing. Good point about those wires. Any time something moves regularly like these timing adjustments there is always the chance of fatigue cracks.

Is this a unique design that Tohatsu uses or is this the majority of 2 strokes? I remember you said they have different designs. Would a 2000 merc 50 2 stroke be the same type of design? I don't have a problem now but am very interested after seeing the vid. I love understanding outboards and learning from you!! I grew up fishing my whole life but we were to poor to own a boat. I always watched boats go buy while i was fishing off the banks. So I've never been shown even the basics.

I have a 1986 Johnson 50hp. I was wondering if you knew what the WOT degree setting should be as well as idle timing degree setting. Idles pretty good, WOT seems a tad off. I just dont want to burn a piston if its too far advanced.

Great video, Stu. Listen, I’ve got a 25hp 2-stroke 3cyl Evinrude that has me pulling my hair out. Idles great in neutral and in gear but if I give ‘er I get about 10% more power and then it just holds and flutters (but doesn’t stall). If I go back down to idle all is well again. I’m going to re-do idle timing adjustment as this is what Evinrude wants me to do next. Would resetting idle timing in itself help me at higher RPM’s you think?

@IdiotVSFish 7 жыл бұрын

So anything past the triangle towards the left in the video will make the spark plugs fire before the piston reaches TDC? If so does this make it run in reverse? I may have missed you explaining this in the video.

@DangarMarine 7 жыл бұрын

Hi mate, good question. I should have gone into the affects of timing more, maybe that would make a good follow up video. The motor always turns in the same direction. When the motor is running faster, the spark fires before TDC, but the momentum of the motor keeps the piston travelling up as the explosion is still weak in its early stages. As the piston reaches TDC the pressure is getting stronger and pushes it back down with more force (in the correct direction), peaking at 20 after TDC. If the spark fires too late, the pressure chases the piston down the bore as it travels after TDC and doesn't add much power. If the spark first too early - the timing is too advanced before TDC it can reach a strong enough pressure before the piston reaches TDC and try to push it backwards. This will cause knocking and is bad.

It has to do with a specified tiny the screw came off after mechanic adjustment and I put in a screw with a washer but was probably not time corrected because the screw fell off after timing it from the Boat Shop was put back on by me Maybe not correct so do you think this could have caused the Piston lowering to crack in Fallout thank you very much

Hey, I was wondering if the specs and procedures were the same on a Nissan 40 model ns40c 2 stroke 2 cylinder. unknown year but I don't think the year matters as much with these Nissan's. I'm having a heck of a time finding this gremlin in my motor that makes it bog down at higher rpm. Great videos, please keep it up. Thank you for taking the time to make them. I have learned so much.

Hi Adam, I presume the Nissan 40c is the same as the Tohatsu 40c, but that is a very different motor to this one. Have you put a timing light on it at higher RPM to see what it is advancing to? If it is bogging down at higher RPM it could also be something like a split fuel hose allowing air in or the fuel pump not being able to deliver enough fuel.

I have completely gone through the fuel system. new lines from tank to car and a new pump. I'm soaking the carb now just to be sure. I that doesn't correct the problem then I'll be looking at the ignition system and timing. I'll have to buy the service manual for all the specs. the fly wheel timing marks have no reference. only a bit of white paint on one mark.

Thanks for for the lesson , is it possible for you to show how set up for a 1983 140 v4 as I think the setting would be different to this video , thanks so much ... Rufus

Mate great video as always. Where did you get the spec's from? I've got a mercury 25 seapro and would like to give it the once over while in lockdown.

Great video Stu have you ever worked on a Yamaha 40hp twin 2stroke BR 40 676s model and approx 1978 think they had the mariner badge in some as I would like some info and timing set up as I can't find a service manual I've watch a few of your videos and they are very good and informative Many thank.

Hi Stewart. No, I haven't worked on one of those. As outboards around here get used daily in salt water they rarely last more than 20 years at the very most so we don't see any old outboards at all. Have you tried sites like tradebit and readmanual.com to see if they have any PDF service manuals available?
