ES Conversion
« on: May 19, 2013, 01:42:47 AM »
Finally wrapped up the ES conversion on the 2011. Picked up a new SP-210 ES motor and robbed it of it's ES parts, the SP is the same motor as the EX for those that didn't know.. Block says EX21. After hours of planning and soldering, It is complete with push button starting on the end of the steering stick. (Thanks for the great idea George)

Will post more details and pictures later, here is the quick video I shot for the first start.

Sweet setup, Tom.  The steering bracket is perfect for starter and plug.  Everything hidden and out of the way. I notice that you don't have to crack the throttle to start the Subi, after governor removal.  Did you use the EX or SP motor and carb?

Thanks, everything worked out better than expected. I pulled the ES parts off the SP and swapped them over, so motor stayed the same. It ran so well, and started without throttle, that I didn't want to bother with breaking in a new motor etc... It will even start cold without throttle, and usually without needing the choke. Another thing I really like over the GX200, is the Subie starter spins the motor over much faster.

Starter button fits perfectly.  Where did you get it?

Tom,  Great to see you, once again, out front on this conversion.  Looking forward to your detailed pic's.  All kinds of questions on this conversion but now all doable with yours and others contributions on this forum.  Thanks again, John

I got the button from Ebay - > http://www.ebay.com/itm/300774684438?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

I made the aluminum insert, button has nut to secure to insert and the whole thing gets pressed into the end of the throttle sleeve.

Thanks, John. The conversion is really a simple matter of swapping parts from one motor to another, then extending the wiring for the key switch and mounting a battery. Getting fancy with building a legitimate harness, adding accessory power and relay for push button, is obviously not necessary, but worth the effort if you are able. Just got back from the river, 15 miles today. A touch of the button and the motor fires right up and idles at 1200 rpm, love it. Look for video later this evening.

Great video, Tom.  motor sounds great with your new muffler and hood mods.  What are your thoughts about GX 200 vs EX 21?

Thanks, George. I have to say that I've been pretty impressed with the EX21 so far. Now that I have ES, and both boats are very similar in weight, the EX is still a solid 1 mph faster than the GX 200. As you saw, a touch of the button and the motor starts without needing to add throttle, something my GX would NEVER do. The GX has been a great performer and I can't knock it, it's certainly easier to find performance parts for over the EX, but now that I see the stock EX providing better performance than the hopped up GX.... I would hesitate to go the GX route again, if I had the choice. The Subaru motor is a well designed performer, EX wins this round.  ;D

That 1 MPH may be from the new hull.  My new hull is a MPH faster than my old hull with identical motors.  I know you will be upping the performance of the Subie.  It is a sweet motor , even when stock.  Your muffler makes a difference.

Good point, new hull is probably the contributing factor there. I'm sure I'll play with the Subie motor one day, for now I'm quite pleased with it just as it is. One of those "if it ain't broke, don't fix it" things. Still need to install my grate, and fill the hull channels.  What do you get for speed, going with the current?

Depends on the current - up to 17 mph

That's pretty good, the KX motor would get the speed back that I lost from the ES conversion. Good to know.

Hillbilly do you notice much difference between the KX vs the modified EX21 with ported ex17 head and jetted carb in performance terms and idle quality?
