The old 1989 88HP Johnson has delivered for years but, alas, it's time has come. I would love to replace the engine with a new Honda 4 stroke 90HP but am a little concerned about weight. I'm wondering if anyone knows the engine weight specs for my 1989 Montauk?
While there is a maximum horsepower rating (100 hp), I have not seen a weight rating. I think the new Honda 90 is fine. It is less weight then it's predecessor. My guestimate is keep below 400 lbs.
I know of several owners with the earlier Honda 90 hp and it is okay. A bit stern heavy but not too much.
This is helpful - but are you saying (because it is on the list) that the nex Honda 90HP 4 stroke is going to be ok from a weight perspective for my classic montauk?
I am going by what people use on their Montauks or 16/17' hulls.
Obviously, the heavier engines will make the stern sit lower in the water. If a person is satisfied with that, then that is up to them.
Several members here have the Honda 90 on the back of their Montauks and say it is OK.
I always leave the decision up to the individual for their needs.
