should be better and I/O are 4 stroke, you'd have to compare 4 stroke outboard to one.

mialage is not a concern of mine go gattta buy fuel there is no way around it but i always use 93 octane do i need to or is 87 or 89 enough. the two stroke outboars on my big boat average about 2.5 when cruzen at 30 knots. but when i am at WOT and doin about 50 knots there drinking about 55 gallons per hour.

I have a 1976 Trojan F-25. It had a Crusader 350 in it. I then dropped a 305 with a higher reduction in it just for kicks. I was not happy. Its an old and heavy boat. I then bought a MerCruiser 454 CID 360 HP and dropped it in. A real tight fit. But I bought it for $800.00 with only 150 hrs on it. I did a compression check and it read right around 140 psi. A big block is a low compression engie anyways. Now you talk about squirrely, if it was not for my trim tabs, I would be in dire straights. She fast but thristy. No a do have a Rochester 4-barrel on the engine. Very small primarys but monster secondaries. As long as I keep those closed, I get about the same milage as the 305 and 350. Torque moves mass....Dirk

About 52 mph.

I am sorry, 52 is wide open, about 27 mph without secondaries....Dirk
