    yamaha 40hp misfire

    Re: yamaha 40hp misfire You are quite right 99yam40 seems my compression testing technique is worse than the compression tester i bought. I checked the tester on my ride-on lawnmower and got the reading back in spec. I then went to check it on the outboard but it just gave up again, so ive...

    yamaha 40hp misfire

    Hello Im looking over a 40hp yamaha 3cyl 2stroke for a friend which powers their boston whaler. They have not used the motor for about a year and recently took her out- she had hardly any power and would cut out. I ran it on a hose and noticed that it had a regular significant miss at all rpms...

    Evinrude 35 solenoid choke

    Hello I have evinrude 35 ecsm (1980) I was hoping someone could please tell me when the choke is pushed in with the key does the solenoid just do one shot of fuel into the carb or if you hold the key in does it keep on pushing fuel through the choke pipe until you let go? thanks

    Redband 50hp Gearbox problem

    Re: Redband 50hp Gearbox problem I put it back on the merc500 powerhead i rebuilt. It wouldnt select reverse gear and then i found out that the large carrier bearing lock nut needs to be done up really tight or it wont select reverse. I think its something like 120 foot pounds but please dont...

    Hi Ive just rebuilt this motor for myself that had blown its big end needle rollers on the top cylinder, a past joker had put in multiple different sized needle rollers on this top cylinder big end.

    Redband 50hp Gearbox problem

    Re: Redband 50hp Gearbox problem Thats it, solved i think. I have no locking pin, looks as though reverse will have to be easy goes it. Talk about past poor workmanship.

    Redband 50hp Gearbox problem

    Re: Redband 50hp Gearbox problem Ok Max thanks for that,excellent point too about the washer and grease. Ive put the fork now facing up. The sticking point i dont get is how does the reverse cam get affected by the fork. All i can see happening (as in photo) is that the two parts would spin...

    Re: Redband 50hp Gearbox problem Thanks Oldman, when i felt that spanner move more i thought i was surely bending something not moving the carrier.Its really nice to finally get a look inside one of these gearboxes.

    Redband 50hp Gearbox problem

    Re: Redband 50hp Gearbox problem Max i think you are right as there just seems to be this sliding pin and pressing on it moves the clutchdog and it springs back, its under quite some compression. Does this mean i dont need to take the pinion gear nut off (as getting enough purchase on the...

    Redband 50hp Gearbox problem

    Re: Redband 50hp Gearbox problem Well i decided to go for it and remove the prop shaft to get to the fallen off cam shaft. I removed the prop nut by using a 24mm and chocking the prop with some wood against the anti cavitation plate. I then heated up the splined washer and knocked that out with...

Johnson 35HP lacking power/torque : Heres a photo of the one ive just done, its for a smaller motor than your one but the principles are the same, ive seen them on motors up to 90hp and theres nothing i can think of that would stop them going on higher rating motors than that too.
