My 1987 Montauk came with a 110hp motor. It seems mighty powerful. Is it over powered?

Sure it must be "powerful" -- only op'd by 10hp shouldn't be a problem ---

1. Look at the identification plate on your Montauk that indicates number of people, amount of weight, etc. and you will see the maximum horsepower your Montauk is rated to use. (If my memory serves, both my '83 and '84 Montauks had a maximum of 110 horsepower)

2. Another issue, at least when you are considering horsepower up near the maximum rating, is to be sure that the boat rating is using the same horsepower standard as the motor rating. At some point, I think in the early or mid 1990's, outboard motors changed their published horsepower ratings from measurement at the power head to measurement at the prop. I don't know the the ratio of loss/gain, but certainly a motor that was rated at 110 hp at the power head is not as strong as a motor rated 110 hp at the prop. The potential problem could arise when/if a (older)boat that was rated for 110 hp at the powerhead was repowered with a (newer)motor that was rated at 110 hp at the prop. The boat would then be overpowered, I'm just not sure by how much.

Weclome back to the real world of snow and ice you old sea dog Kingfish --- hope you all had fun.

The Montauk is rated at 100hp max.-- that is from a late 70's spec sheet and a mid '90's one, rating hasn't changed since day one ---
