Over-powering the boat (i.e. going above the HP rating for the hull) would be a more likely cause of damage to the transom.

The weight of the engine is primarily an issue for trim, i.e. causing the stern to squat too much. I don't know the weight of that engine, but it is probably above the original design weight for the Montauk 17 (which was released in the mid-'70s when much lighter 2-stroke engines were the norm.)

Trim can be somewhat corrected by moving other weight forward, for instance by relocating the battery to the center console.

The much lighter Yamaha 70 HP 4-stroke is a popular choice for the Montauk 17.
