i have been working on a 1974 magnum 25 sport and will be putting a sinlge 502 with bravo 3 in in instead of twins. i was looking for a paper template and also information and input on where to mount the drive. we are starting with a fresh blank trason and new stringers and were wondering if we should favor a higher mount or a lower mount. we are not looking for all out go fast because its more of a bar cruiser then go fast now. we will be having a crowd on the boat and need the boat to jump up on plane but also still top out reasonably. and input or experience is welcome. thank you
