I've just moved from a '90 21 Daytona (GT200 Johnson ) to a '91 22 Daytona
tall deck with a 454/Bravo 1. The old o/b boat ran mid 70's everyday, handle very crisp and really responded to trim well. The new (to me) 22 feels like a yacht compared to the 21.
When I bought the boat I was told it was a 350hp 454. It has a Holley DP on it and what sounds like a tame cam, stock mercrusier exh manifolds, thru hull only. It has a 1.5 Bravo 1 drive and a Mirage 25p prop. I'm getting 50 mph at around 4200, not exactly what I expected. It does not respond to trim like my old boat. I get alot of porpoise and the prop will blow out if I punch it out of the hole, trim all the way down.
This Mirage prop is a little ratty looking, could that slow it down alot?
Should I investigate a 4 blade Bravo to get the bow up and control the blow out?
Any idea what I should see in this boat with around 350 hp? I thought it would run closer to 70. The motor sounds good, has good midrange but nothing on top. It apparently only has 90 hours on it.
The boat originally came from Tennessee and had a twin turbo setup.
I was told the guy grenaded that motor and replaced it with what it has now.
Any suggestions would be appreciated, before I drop big $$ for a nice blower motor ;-)
