I'm in Maine and have a 2010 Prodrive with a 27 hp Kohler. I'm wondering if anyone has ever replaced that engine with a 36 Vanguard??? Will the new engine bolt right up to the existing motor frame??

There's not much market for used mud motors up here and I would like more horsepower. If upgrading the engine was feasable, that would probably be the cheapest fix. My motor already has reverse and power trim

Yeah, it will bolt right up. Very easy swap. Depending on where you order the engine from, you can probably get a 36 with the same wiring harness also.
