Replacement Engine Question

[nymack66]

With my 140 on smooth Lake I once saw 39-40 never did tried it again, I am yet to set my WOT timing so I stay under 5500 RPM..

So a later model 115 would be a good fit for a V?

I am just looking for something dependable that will plane the V and cruise at a decent speed, say 25 - 35 MPH.


By the way, I never hit 45, the first year I owned the V I was hitting 40 and then each year
I noticed a reduction in top speed, I should have known then that I was losing compression.

Parish that is what I had on Old School,, works just fine

Thanks Willy.

I am at the point in my life were speed does not matter,
I just want to get there, drop some lines,
take a nap and then get back.

If you can find one of the 95+ 115HP OMC loopers then jump on it. They are not speed demons, but they are fairly quiet for a carbed 2 stroke and you can't beat the reliability of them. The 90-175's that were refferred to as the EAGLE series by many has been argued to be the best engines that OMC EVER built.

The Johnson 115 on Old School topped out at about 34 mph this season based on the gps. I cruised around 25 mph. I think more could be achieved with some tuning and prop optimization.

Thanks whale,
those are the type of numbers I am looking for.

So this gives me a good range to look for, 115 to 200.

Hey Parishht - Not to bust your balls too badly here, but what HP were you looking at before???? 25hp - 90hp???? I know I'm an *** :)

Unfortunately with the low 20" transom you are limited by weight.

I imagine that you'd want to keep the motor weight under or close to 400lbs which significantly narrows your choices (eliminating almost all newer v6 outboards).

As mentioned before your best choices based on price, reliability, fuel economy are going to be the following. I think you mentioned that you wanted to keep your OMC controls . . . so if you have the red plug . . . you are looking at 1995 and earlier.

v4 OMC 115 - 130, 140
v6 OMC 60 degree 150 or 175
v6 Merc 2.0L, 2.4 or 2.5L
V6 Yamaha 150 - 200 2 stroke carb.
v4 Yamaha 115, 130

For a 115 OMC make sure it is the late model looper as they are much stronger than the earlier cross-flows. My V-20 would hit 27-28 with just me in it with the 84 115 it had on it. There are quite a few 120-140 85+ loopers out there and they are good engines. There a bit heavy, but pretty good on fuel. A 2.0L or 2.4L MERC, and the 150-200 small block YAMAHAS are also great choices like BS said.
