Hey everyone, so I got one of those cheap induction tachometers to use for tuning my outboards, the ones with the long wire you wrap around a sparkplug wire. I set it up on a Honda kicker and it seems to work well. When I set it up on my 50hp Force, I seems to get 1600 Rpm at idle. Did I set...

I have an 88 50 hp force, do all these have overheat buzzers? I'm not sure I mine does. I'd hate to burn up my motor. I added a tell tale that pisses like a racehorse, but I don't know if I should rely on that. Thanks!

My motor is a 507y8c. Would this set work? https://www.offshoremarineparts.com/12-11-574.html Okay are referring to the o-ring numbered 25-201951?

Okay I copy. I will do that.

Hey did this fix your problem? I think I may be in the same boat, no pun intended.

I understand, but I'm running out of options I think. So far, spark is good, no vacuum leaks, carb is clean, rebuilt and tuned, fuel pump appears to be working well, compression seems good, water is flowing well (blew a gasket so maybe too well haha), fuel tank is good. All I can think to check...

I will definitely be checking that. I need to pull the powerhead off to replace some exhaust gaskets anyways so I'll do those at the same time. I read a thread on this site with guy with an 85 hp force with the same exact issue. Seafoam dislodged carbon chunks which plugged up his recirc. Plus...

Okay sweet thank you! I wanted to be sure I understood the system correctly so I order the right gaskets. Which gaskets would you recommend I order? I want to make sure I get the right ones.

So here's what I found in my clymer manual. I think this hits the nail on the head and I'm curious what you all think. So the manual references the fuel recirculation system, which feeds unburnt crankcase fuel back into the cylinders. Fuel pools during idling and gets fed back in to be burned...

Okay, I've read a couple posts also referencing these water leaks, where does the gasket fail and how do these leaks form if the pickup connects directly to the motor?

Also just out of curiosity, where does the water pickup tube actually connect at the power head? Is it somewhere under the starter?

Im just saying that because I have the same motor and that is what happened to me. Bad stator and bad trigger. I didn't test it myself, I had a trusted mechanic diagnose it for me. I had figured it would cost more for me to throw parts at the motor than for me to pay the mechanic to diagnose and...

Ooh okay I see what you mean. Yup I'll be sure to be extra careful spraying that stuff in the future.

Yup copy that Chris 1956. However lack of spark does not appear to be the issue.

Okay I see, yeah the clymer manual definitely leaves a lot to be desired. Okay I see what you mean about the extended idling, but how long is too much? I maybe had it idling for 15 minutes at a time. Isn't the fuel recirculation system supposed to alleviate this?

Oh one time when I ran it after the trigger swap. Normal amount of smoke then. When I took out the next time I added the seafoam to help degunk the inside. Maybe a teeny bit more smoke then, probably the seafoam. This was two weeks ago. I didn't have any serious smoke like this until this weekend.

Oh okay yeah that's what I thought. I figured the color was normal but the volume was excessive.

Blue smoke is uh oh? This is a two stroke so shouldnt blue smoke be expected? Before the seafoam there was very little smoke. The fuel I was using did have some seafoam that I added just as a light cleaner and fuel stabilizer. The motor ran as if all it needed was some very slight adjustments...

Ahh maybe a whitish blue. Like when you do a seafoam shock treatment.

Wow lots of replies! Topgun, would the clymer manual suffice? Nordin, yup that's what I kinda thought. When I replaced the trigger, the new one came with the little arm. I just adjusted the new arm so that it was identical in length to the old one. Would a very minute difference result in this...
