1970 Aquasport 170 rebuild

Cat...as you've said, you're basically looking to replace the port-side stringer. For ease....how about a combo of the ideas you've mentioned? That is, on the replacement stringer, forget the mold ($$$) and go with coosa glassed-in to form the new stringer, foam-filled, with a "permaloy" synthetic top.

Basically the same as what you have, but stronger, with the ability to place screws in the permaloy. Will be less money than taking a mold off the other stringer. And since the deadrise angles are reversed, a potential can of worms. Plus...a bear to get the deck height correct side to side.

Probably easier to just run strings, and build to the strings.

Best wishes for the upcoming school year

Cat,

I don't think I would add a bracket or anything else that would move the boat's original CG further aft.  In a smaller boat that shift aft will be more dramatic.  Plus, I like the traditional lines of the 17 (my opinion).  I did add some height to my transom on either side of the motor, the thread below has some pics.

These boats were designed back in the day for a specific HP range/engine weight.  Boats built today are designed with 4 strokes in mind which are generally heavier.  I would try to stay in the same weight range as the original to prevent weight issues at the transom.  I did add height to my deck and rasied the transom drains slightly and have no issues with draining.  I do have a 2S 90HP Yamaha on the back and have been very pleased with performance etc.  Not saying you can't go with a 4S, just be conscious of the weight of the engine in comparison to the original.
