Mariner / yamaha 30

[Roflhat]

Looking for some info on these, the 2 cyl ones. Came in 25hp and 30hp as far as I know. What kind of crank have they got? Is it pressed together or a solid steel one like the 55hp 2 cyl? How can I disconnect the rev limiter? Can I get boyesen reeds for it? Will the 55hp 2cyl carbs go on?

Cheers

Crank is one piece. No idea on the rev limiter.

there is two version of cdm ignition in this motor.the one with TPM 'timing protector module"(this not the one we want) , the one with rpm limiter( this is the one we want) just remove the limiter than you are good for 7000rpm !

Thanks guys. I'll try and get a picture of it today. So if it's the one with the limiter which wire do I cut?

[lcp]

just remove the entire unit.
