I will. I added 15 hp to one of my boats and more than doubled my
speed. 9.8 HP outboard = 7~8 mph I switched to a 25 HP = 20~25MPH
depending on load. 15HP increase = 13~17MPH speed increase. on an 16'6"
aluminum boat.

Tony, don't sound like anyone believes you with the 15hp = 1mph faster! I
do!

Unless you are rebuilding the engine anyway, I would not waist my money.
It takes a lot of hp to gain any real benefit on the water. Most quote
15 hp to 1 mph. Spend your money on a 350 assuming your boat is 18' or
bigger. A 17' will probably run sideways from the torque.

Biggest bang for the buck is usually found by going to a good performance
SS prop. You can see 5 mph gain with the right prop over a cheap
aluminum one.

I have done some research and heard you can put higher compression
flat-top
pistons in the 4.3 and gain a few HP. Who makes these pistons? I have
done a
bunch of searches and come up empty handed.

A related question, I have also read that the 4.3 is a 350 minus two
cylinders and that the pistons and rods are the same. Is this true or
false?
