how fast does your boat go?

Sounds to me like you could use more pitch! is the ratio engineutput or vise versa.... so your output isn't as fast right? i borrowed a higher pitched prop from a friends boat, just changed it in the water, and took for a drive and loved it. could try that before you drop $$

 

We have an Xpress bass boat with a 90hp Yamaha on it. Gets up to around 40.

 

I have no idea what my drive ratio is

 

Yeah I've got good holeshot with a light load.

That's what I'm thinking to but it could just as well be my tach and I probably could get more top end if I stayed wot longer and trimmed it out ideally but I don't want to hurt it if it's really running that high. I've only done like a 10 second run at wot. In all honesty though I don't care too much about another 5 mph but more so about the boat running in the right rpm range.

 

Even with my higher pitch i can get right on plane with 10 people + camping gear... no thats not legal. but the easiest way to get 10 people and camping gear out to a nice little island in the bay. the hydrofoil makes a big difference.... especially turning, can basically be on its side at full throttle without cavitating

 

We got a kawasaki zxi 1100 with racing prop and impellers that would run 73 with two people and my dads 95 javelin will run about 62 on a good day

 

I know they are made for it but I don't want to be over revving it for too long if the tach is correct.

Damn. That must be scary until you get used to it.

 

right around 50 mph for my flats boat... my 14 Jon boat does around 30 mph.

But my e tec goes for ever on a tank of gas.

 

My boat mechanic told me that running the boat just shy of wide open is the best place to run an outboard. That way the gas/oil mix burns completely and doesn't leave carbon deposits in the engine.

I have basically the same boat as Chris 4x4 its a couple years older and about a foot and 1/2 longer. I got it up to 45 with a four blade ski prop. I added a hydrofoil stabilizer and lost a mph or two but it rides a hell of a lot better.

 

Ya it was! you couldn hold it wide open for long becuase ur eyes would start watering. i had to start wearin glasses and i cant count how many pair i lost=[

 

Hydrofoils suck trimtabs are the way to go

 

as fast as I can paddle

 

Gets me all the chicks on the lake.

If there fat they cant outrun me when they see me coming.

 

we have those fat chicks on the water. They are called Manatees and the fish and game commission makes special no wake zones just for them.

Yeah they kind of look like that.

 

Caugh:::::: Bull Shit!! May be close to 60 or 55ish not 67 get a GPS my 18ft 1600 lb 200hp Procraft fish and ski only does 60 GPS but my speedo will tell me I'm running 70

 

45 mph. Next Season, i'm gonna install a '' Sting Ray Hydrofoil Stabilizer XRIII '' on my Engine, & Change the Prop. search for at most 53-54 mph.
