    Wanted, ZT280

    I drove 700 miles round trip to look at that ZT280. Had 35,000 cash in my pocket to buy it. I was there for 4 minutes. Left without the boat.

    Wanted, ZT280

    I’m looking for a nice ZT 280. Looking for a decent deal. Not looking for a project boat. Must have a trailer also. Under 35,000.

    Severe Porpoising

    Ive been through he same issue with my 251. I installed a Stingray Hydrofoil and it helps a lot. there is no down side effects that I can notice with it on the drive at any speed. Also, 'seat time' will help you learn how to manage this hull. It's truly a 'drivers' boat. i'm constantly adjusting...

    Prop Help

    I may be a little late, but if youre spinning the mirage at 4800, I think you'll spin the Bravo 26 even slower. I think a Bravo 24P would be a better try.

    Procharged 502 ZT280

    The 2 boats I put superchargers on were running mid 50's stock and then 68-71 after.

    Procharged 502 ZT280

    Ive put 2 superchargers on boats, both with stock engines and both running 4-5 lbs of boost and both boats gained about 13-15 mph.

    Convincor LS Swap Project Thread

    I love happy couples and families!!! nothing worse than having "friends" that always argue and fight when you hang out with them, and nothing better than to hang out with couples that love each other and are fun and happy.:cheers:

    Merc or After Market 'Safe/Child/Wife Mode'

    Hmmm... interesting thought. I know Ford cars have that option. They can be speed limited and radio volume limited......seems like boats are usually ten years behind on the technology.

    Mercruiser 420 with a Weiand 177 blower?

    A couple years ago, I pretty much tried to blow it up so I would have an excuse to build another engine. We ran for about 10 miles down river at 90-100% throttle the whole way. We were running 65-70 most of the way and then 71-72 at WOT for a mile or so at a time. I don't remember if that was...

    Mercruiser 420 with a Weiand 177 blower?

    The engine had fairly low hours when I put the blower on, about 150. now the engine has roughly 300. No issues with the Bravo, I just change the gear oil every few years. I run premium pump gas, mostly 91 octane, sometimes I get fuel on the water and then its not premium, I think 87 or 89...

I used the same carb same stock iron exhaust manifolds and same ignition. It ran high 60's...like 68-69. Ran that...

    Gear sets and ratios.

    The 1.32 gears will spin the prop faster than the 1.50 gears at the same engine rpm. The gears we are talking about are at the top portion of the Alpha and this is the weak point of the alpha. Usually when they break because of too much torque, it's these gears that break. I don't know about the...
