I had the Merc version of this engine which is even heavier. I had it on a 16 foot mirrocraft and I weigh in at just over 200 lbs. performance was abismal. ... could not compensate for that heavy engine in the back + my weight + a small battery. Great engine for a party barge or another boat but the 25 was NFG for my 16' . Hard to get on plane & constantly displacing water instead of riding on top, trolling of course was great.
Solution ? I took it to Port Colborne Marine (where I bought it new) and had a power trim / tilt put on it still NFG. Then had problems with the trim & tilt ...took the engine back for warranty work @ 20 hrs use...the thing got ripped off! While in a compound in Port Colborne reportedly patrolled by big bad gaurd dogs! Had the thing a total of 8 weeks!
It gets better ...they (the dealer Pt Colborne Marine) don't cover it it comes off YOUR INSURANCE.
WOW felt like I just got out of a maximum security prison in the deep south, with a cellmate named BUBBA if you know what I mean.
Bottom line it's a great engine but way too heavy stick to a smaller 4 stroke (15hp suzuki) or a 2 stroke for this application.
PS want to sell it to me ??????? I now have an 18.5 footer![/b]
