A tee top does not belong on a Montauk, period. The guy who installed had no clue. I would get rid of it. Whaler used to say they can make a small boat like a 1988 Montauk unstable in wind and rough conditions.

Regarding the engine, your buddy is misinformed. For about 5 years, the last years of the classic Montauk through 2002, BW factory installed the "Mercaha" 90 HP 4 stroke on the boat. It had a listed weight of 388#. So we know the boat can handle it. For many years prior to that, people were installing 10 HP kickers on Montauks equipped with 90 HP 2 stroke engines (about 300#), a total weight of around 400#. BW has said the classic Montauk is rated for 410# of engines max.

My Montauk carries a 305# in-line 6 cylinder Merc "tower" very well, with no stern squat at all, and it accelerates out of the hole like a rocket. No transom stress cracks whatsoever.
