re-powering old Tyee 5.5

[raf2325]

Hey guys,

First time posting here. Not sure if I'm in the right forum, feel free to correct me.

I have an 1986 Lund Tyee 5.5 that I am looking into replacing the outboard on. My main concern is the extra weight of a new four stroke. I'll start by staying it was my dad's boat he bought in new. It was powered by a 1979 Mercury v150. It was later re-powered with a Mercury 125 two stroke, which has that cylinder shutdown. I think it sucks. So, I'm looking into new mercury 150 four stroke, I know it's a lot of money for an old boat, but, the transom had been replaced and it does have some sentimental value.

So, is a new four stroke too heavy? (about 480 LBS) The current motor is about 360 LBS, give or take. I know the boat was designed for the lighter two strokes of the time.

Any input is appreciated! Thanks

That hull is a tank, it really doesn't need a 150hp I had an 1983 with a 115hp more than enough power to pull a skier and tubes.

What’s the weight of a 140hp Suzuki?
Or what’s the lightest engine in 100 to 150hp.
I’d take a 360lb 125hp engine over a 480lb 150hp. You have to check the different brands.
That said some boats need max hp.
