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.
Larry, I'm surprised to read that number (410#) for the Montauk 17. When I contacted BW about the max engine weight for my 19 Outrage II, they told me the max design weight for the Outrage 18 hull was 400#. They were not able to find the spec for my boat, but suggested it should be the same as Outrage 18.
I'm inclined to believe them because my +/-450 lbs Yamaha 150 (with oil tank) puts the scuppers below the waterline. I'd like to think Dougherty didn't intend that!
