I have the chance to replace my 65 h.p. Johnson with a 2000 90 h.p. Johnson. The motor has very low hours and looks like new. Would this be too much weight? Opinions please.

Of course the 15 is rated to 70 hp, and mine had a 70 Yamaha, and it was fast enough to scare me into buying a ne 50 Merc which still gives me 39+ mph. The motor weighs about 230 I believe, and it's about all the 15 can handle on the rear (the transom well drains are just barely above the waterline.
The 90, if it's a 2-cycle might be in the same weight category, but I'd buy additional boat and life insurance.....

Well, ya got the right name fer it!

My capacity plate says the boat is rated for 75 h.p. I understand that it would be wicked fast and not a boat for kids, but I saw a 15 a few weeks ago with an older inline 6 Merc on the back and it didn't look too stern heavy. Before I saw that I wouldn't even considered it.

The 6 cyl "tower of power" motors are not too heavy at 300 lbs and the 90 hp weight the same as a 150. (hint, hint) :)

Besides hinting I think if the boat is not kept in the water it will handle it fine. I was in a 1978 15' in Barbados with a 115 ocean runner. Boat hauled booty! It did not sit that low and handled fine although it was hard to get it over 4500 rpms ;). The boat also had not ONE stress crack in the transom. When I redid my 15' CC I wanted a 115 but could not find a decent used one. I finally found a rebuilt 70 for $1450 and could not refuse that deal. I think resale will be very difficult with that engine plus you will need additional insurance. Other than that.....let her R.I.P.

I have a 2002 Johnson 90 - it weighs 335#, IIRC. You could look the weight up on the Johnson website.
BQUICK - the 90 and the 115 weigh the same (both use the same 4 cyl. block), but I think the 150 is a 6 cyl., which would weigh substantially more.

he was referring to the old 150hp inline mercs which weigh the same as a 90.

Oops...never mind.

Thanks for the replies. Turns out I won't be buying this motor. If anybody's interested, Becks Outboard in Jacksonville will have for it sale in a few days. It's a very clean low hour motor.
