Adding electric start to a 25hp 2-stroke outboard

[gronski]

This is almost a double post as I have already posted a question about a rectifier, but I feel that the pull start to eleectric start is really a seperate question. So here goes...

I am considering purchasing a 1994 Yamaha 25hp pull start 2-stroke outboard. What parts would I need to convert it to electric start? How much weight would that add? Would I get a battery charger too as part of the electric start system?

Thanks,
Chris

Chris,
25MSHB is a 2003 model - a 1994 model would be a 25MSHS - which is it ?

Chris,
Looking at the diagram of your motor in the online catalogue (above), I'm having a hard time determining if you could add a starter.
Assuming all the mounting holes are in the block, you would need a starter, starter relay, a flywheel, a starter switch, and associated wiring. It would be a pretty expensive project.
Try posting your question again as a new post - late at nite, so that boats.net mechanic can answer you the next morning - he seems to answer most often those posts that don't have any responses yet.
Good luck [img]smile.gif[/img] ,

Ken is right, very expensive. Yamaha doesn't make an elect. start kit so you would have to buy all the parts separetly. If you price the parts Ken listed you will see it is expensive.The last 25 elect start was in 1998(25ESHW) and I'm not sure if all the mounting holes are still casted into block, I think they are, but if you get serious about it I will check into it.

At this point I am just kicking it around as an idea, don't go to too much trouble.
