Take out the inter chamber an reroute the water first.Cut pipe off about 6 inches or make new pipe, you can cut open exhaust in bottom of tower or side of unit.Just drilling the unit will only make noise.

What I have here is a 2 banger omc.... on a 15" fishing motor midsection. was wondering how to make exhaust exit better. what I plan on doing is drilling holes in gearcase. What I have found is that drilling out gearcase just gives you the "sensation" of speed. Thats what I call it anyway "the sensation" of speed.
What my big plan is to install motor on scat cat.....

Hey Fred,
was interested in the carbs you have for 2 banger, but unsure of what needs to happen with boost ports and such to make motor "come alive"
Your input would be great... I have a newer 50 block I would like to install or have installed boost ports installed. Have crank sent to fix and maybe lighten????? any thought more than welcomed.....
