What a difference the electric start makes.   I put it in a few weeks ago but just this past weekend had a chance to take it out.  I can honestly understand why some people put the Mokai up for sale.  The pull start is tough on a person my age, or as a matter of fact ANY age.  You just don't get the leverage you have when you are standing over an engine like on a lawnmower or a go kart.  When you are sitting on your butt and the engine is behind you it is a chore pulling on the starter rope.  I can see why Mokai went to all electric starts on their boats and it makes a lot of sense.  After taking everyone hints on how to do it and put the starter button on the throttle handle it made going out in the Mokai very enjoyable.  I will work on the muffler this winter but for now just going up the river is now fun again.

Hey Maxtorque. Glad you made the install. You're going to enjoy the upgrade. Especially after contending with the manual start. Don't worry about your shoulder anymore.... Just worry about those 2 fingers that turn the key.........LOL!!!!!!

I'm working on moving the ES components from an EX17 I just bought to my EX21 (2010 Mokai).  I've got the flywheel, starter cup and flywheel cover moved over.

I thought I was going to pull the recoil starter out of the EX17 and put it in the EX21's recoil starter HOUSING - but it doesn't fit, its too big.  I tried the complete EX17 recoil assembly, including the EX17 housing, but it doesn't fit inside the plenum ring.  What's the trick?  Do I cut down the EX17 housing to fit inside the plenum ring?

In the meantime, Tom's working on the wiring for me (and a pump rebuild).

Thanks.

Interesting, wasn't aware size was an issue with that. I know the EX21 recoil starter won't work with the EX17 flywheel cover, not without spacers, 1/4" foam ring seal, and longer bolts. That is how I handled the ones I've done, figured it would be easier to swap over the EX17 recoil but I guess not. Is it a diameter issue that trimming would solve?

I have just cut the starter hump from the EX17 cowl and pop riveted it to the EX21 cowl (after cutting clearance hole).  Then use all the EX21 stuff.

Thanks Tom and Hillbilly.  I ended up using the EX17 recoil starter case and just trimming it down on a bandsaw to fit into the plenum ring (primarily around the bolt holes) and also removing one course of louvers with a dremel to make the case a little shorter so that the ratchet fit properly into the starter pulley.  I also needed slightly longer bolts to attach the plenum/recoil starter to the blower housing due to going from a metal recoil case to a plastic one.

Good job, ingenuity like that is what it takes to keep these boats fun. Thanks for sharing what it took to make it work. Will you be using the EX17 head on this motor too?

That is probably the better route. Hadn't considered that, good stuff.  \./8

Thanks Tom.  I think I'll do the head swap from the EX17, but not anytime soon.  Maybe over the winter.  I've never done work like that before - and I want to actually use the boat a bit once I get the pump back!  I've only actually been in it twice so far!

Are you looking to convert a Honda boat to Subaru ES, or just convert a Subaru to ES?
