Motor replacement

#1 Post by Marcus Merriman » Fri Jul 31, 2020 1:57 pm

We have a 1991 Harris Floteboat - Sunliner 20' w 40 hp Evinrude motor. Something happened toward the end of the season last year and reverse was lost. Forward still fine. Diagnosis points to lower unit - controls and cables are working but there are metal shavings in the lube oil.
The problem has been finding a replacement lower unit.
My main questions now are :
1 - can a lower unit be rebuilt instead of replaced ?
2 - can we consider a smaller motor, like a 9.9hp? We use the boat on the Erie canal where we are virtually wake free zone wherever we go. Just want to get to the bars and restaurants.

Looking for any advice for this situation.

Thanks in advance,

Marcus

I would think any outboard repair shop could do it or if your handy, give it a try. Look online for parts and service manuals that are free to give you an idea of what is involved before you start, voice of experience on that....
Have no idea if your controls will mate up to a smaller outboard, most seem to be tiller steer, but worth a look. Some around here have 20 to 25 horse on them. Would a 10 hp push it well enough? 4 stroke is the way to go, Repowered mine with 50hp
4 stroke from a 50 hp 2 stroke, world of difference in fuel consumption and noise for the better. Needed to update controls and wiring though.
I boat on the western end of the Erie Canal and into the Niagara River.
