130hp on a Montauk?

What does everyone think about putting a Johnson 130hp on a 1990 Montauk?

In my opinion, the Montauk doesn't need 130 HP. My recollection is that the Johnson 130 weighs something like 365 lbs so it exceeds the transom weight limitations by about 35 lbs. If you are thinking carburated Johnson, you would be much better off with the Johnson 115 or 90.

It does not exceed weight limitations which is just over 400lbs but that is a heavy biotch. I have however seen a few with 120's which is the same engine.....guess it will be ok.

BIGS.. Something doesn't make sense here. The commercial version of the hull has a weight limit of 330 and the rec vesion 410. What is so different that the commercial version that it gives up 80 lbs of capacity? The extra glass can't be the reason, can it?
Based on Whaler's previous incorrect published weight specifications for several hulls, can you trust the 410 figure?

I have a merc 100 2 stroke at 365 lbs wet.
I had a 90 hp merc 290 lbs for 20 years ocean and freshwater. Do not like the way the extra weight on the 100 affects the handling, sits low in water, porpoises. I am in process of replacing it with another motor to keep total transom weight around 300 # which I think is ideal. But that is just my opinion.

I think it has to do with the extra glass and swamp capacity, etc.
JCL....you are also running a kicker....correct?
I had a 260lb Yamaha 90hp and now run a 340lb Zuki 4stroke and a 20lb +/- jack plate. I think the Montauk handles BETTER with the added weight. If you drive in some chop you will lose your fillings, now put someone behind the seat and notice how she drives softer. I do NOT porpoise and I do not have a doel fin, etc. I really think the porpoising issue is with prop selection. Most who have porpoising problems have mercs and maybe they give too much bow or stern rise, etc. With PTNT that should not be an issue at all. I can make mine porpoise, but I can also stop it:)
You will not have an issue with weight and she should FLY! DO you trust the transom enough? Weight does not ruin transoms....HP does, mainly on holeshot.

S.C. DNR has commercial 17's w/ 140s on them.

Some of the CPD whalers have scuppers and some don't(ie Alert models). A self bailing Montauk is a pretty phat setup. But if you exceed 330lbs is water going to back flow into the scuppers at rest? It would be interesting to check with the SC DNR to find out more.
