People shouldn't quote speeds unless they are GPS.

Re: Estimated top end speed???
 

yeah, i used the "Speedbox" app on my iphone. I assume you would qualify this as a GPS? I only checked it once, but its always accurate in my truck and on my dirtbike. If you don't already have it, give it a try.

Re: Estimated top end speed???
 

I use my phone also. GPS is GPS, so it's accurate, unless it's locking up like my Droid likes to do.

My 20 ft Z202 with a 260 hp 5.7 Merc Alpha 1 did 53 with just me. But now that I have a bimini and smart tabs, it's dropped to 50.

I don't see how yours could be so much faster.

My 222 has a chevrolet fuel injected ram-jet 350. From what I've been told, it is not a normal boat motor. I'm not sure of the exact horsepower. I'll take a screen shot of my GPS when I'm out next and will post it to this message board. If your wanting more speed, i suggest getting a ram-jet. Its about a $7,500 motor, not counting installation, etc... I don't have trim tabs and neither of the bimini tops are on the boat right now. I was told that once the motor is broken in, a computer could be connected to it and adjustments can be made to increase the horsepower and increase the top end even further.

Re: Estimated top end speed???
 

I want one! I would love another 100 hp! I heard that changing from EFI to MPI would bring me up to 300 hp, right?

I would love to see some videos. Not because I don't believe you, just because I want to see it in action.

Remember, non-marinized engines are a ticking time bomb. A car engine is NOT a boat engine. It can be done but there are a lot of modifications that need to be done to do it properly. Starters/alternators/distributors, pretty much anything elextrical needs to be marinized or you are just asking for a fireball on the water. The good news is, the water will eventually put out the flames..... while you are swimming away. Hopefully whoever did yours did it right!

And engine is an engine, it's the bolt on items that are marina specific. I would hope it's all been converted, but if not, it wouldn't take a whole lot of effort to convert it.

If it hasn't, remember, if you blow someone up, you'll be in big trouble.

If an engine is an engine... Why are "Marine" intakes banned for stock cars?

You mean like NASCAR?
