I tried to do some searches but couldn't get anything that I needed to know. I was wondering just how difficult it would be to swap my older 18hp vanguard on my GDLT with a 35hp vanguard. Ive never swapped an engine and never seen it done so I was wondering just how difficult it would be. I know if I swap engines I will also have to swap props as well but just trying to find out exactly how hard it would be.

The mounting holes and crankshaft height are different. It wouldn't work.

Okay thanks. A guy that rides with me told me that his friend had an 18 and switched it up to a 35 so I wanted to make sure it was possible
