I currently have a short shaft Tohatsu outboard which charges my batteries; but comes out of the water if I move away from the stern.

I'm considering replacing with a manual start 15 hp evinrude which doesn't appear to have any charging capability but it does have a long shaft (I already own the evinrude--it needs some work: see previous post). According to a local Tohatsu rep; extending the shaft is very labor intensive requiring removal of the power head.

Anyone have experience extending the shaft on a Tohatsu (late 80's model).

Maybe I'll sell both and get a new XL OB...

Albert,

Maybe you could add a solar panel or two for less than the cost of extending your Tohatsu lower unit. In this photo, {[url="http://www.trailersailor.com/uploads/1_c25_afthalyards_01.jpg"]link to C-25 dual solar panel photo[/url]}, each 11w Unisolar panel (approx. $100ea) is wired directly to a group 27 wet cell deep cycle ($50ea at Sam's Club). Not that I'm discouraging you from having an extra long shaft motor, but maybe this way you could use the older long shaft OMC w/o alternator. I firmly believe getting the prop deeper is better. On this boat, I also have a shore power charger, but on previous boat one 11w Unisolar panel kept a group 24 fully charged and then some (weekend daysail usage pattern).

Hi Albert...

It seems to me you're not new to your C-25, but I'm wondering what sort of waters you sail in. If your Tohatsu "comes out of the water" when you move forward a little, it'll be in big trouble if you get into some serious chop--not just for thrust, but for cooling. My previous 22" long shaft Honda (from the DPO) gave me similar problems, on Long Island Sound, to what you describe. All opinions were that it wasn't worth trying to extend it, so I got a pretty nice price for it and went XL.

I'd believe the rep, but I can't tell you whether the Evinrude is worth fixing up. In my waters, longest is best, but I had to redo the bracket as well as the motor to get there (a 28" shaft and a 14" vertical travel bracket for a high-thrust 4-cycle). That was a serious investment, but I have no aspirations go bigger, so I decided to get it right.

If you're using it in relatively protected waters, that Evinrude may be worth a shot. Leon's suggestion is a good one for that circumstance.

Dave, thanks for your perspective. I usually sail in very protected waters (25 knots wind = 1 foot chop) and completely neglected to consider conditions in other areas. I think I'll sell both and go for the XL Shaft.

Now the hard question...4 stroke, 110lbs, new motor mount, or 2-Stroke 80lbs, same mount....Hmmm....
