Great Pics. ;)

Re: First trip in the salt with the 250
 

Thank you everyone for the compliments on the pics and the movie. Now that my kids showed me how to work Windows Movie Maker I'll be using it more often. It's great to be able to string together the 15 second movie clips that I can take with my digital camera.

Shawsee,
I lauched from Taylor Point, in Bourne. Good ramp and facilities for $10. I'm not familiar with Maco's, is it the place just across the bridge? Any closer to getting the brakes yet? And yep, the Rev. got ahold of me and said if I didn't get all PC and declare myself a Ho free zone he was gonna shake me down. Plus it looks like my name was already taken...

I'm really happy with the boat. It's not too big or heavy, my 1/2 ton Suburban pulls it just fine. The cabin is actually big enough to be useful and there is still a good size cockpit left over. The enclosed head is more trouble than it's worth for guys but it does solve the biggest problem once you bring a girl aboard. Performance is good enough for me with the 220HP motor but since it is 21 years old (and requires 93 octane gas) I'm keeping my eyes open for a good used repower. I'd like to stick with a Yamaha, probably a 225 or 250 but 300HP would be fun, any recommendation on years or models to look for?

One gripe I have is that there is no anchor or rope storage in the bow. I can probably make a pulpit but I'm looking for ideas on rode storage.

I would reccomend a late 90's 250HP YAMMAHA OX66 if your looking for a easy replacement and reliability.

Re: First trip in the salt with the 250
 

I remember back in the mid 90's that the 250 Yami's changed from being GAS HOGS (1 mpg on a 25 ft boat)to doing pretty good on gas (3 mpg on a 25 ft boat), just be sure to get the latter.

the VX-76 250( had 6 1 bbl carbs) was the fuel drinkinest motor to ever be bolted on the back of a boat(except for the V8 Johnrudes). They told me in Yamaha school it burned between 41 and 44 gph @wot, they used excess fuel to cool the combustion chamber and keep it from blowing up. The OX series fuel injected motors were far better

Re: First trip in the salt with the 250
 

Say it aint so, please say it aint so. I have a 93 250 YAMAHA I was going to put on my 20' HYDRA-SPORT CC. I had no idea they burned that much, I think the 4.0L V-8 JOHNNY-RUDE only burned 30-32 GPH top end though.

EXCESS FUEL?? ??? ?? ... boy, now THERE'S a term from a different time ::) ... back when oil company magnates were shrewd businessmen instead of the GREEDY-A$$ Bean-Counters they are today ::) ...


...anyway MB...great trip in the 250!! 8) ...and I REELY like the white bikini lower left of last pic ... GREAT camera work 8) 8) ...

i have one customer that has a VX76, he said he keeps it around 3500 and it doesn't do too bad( he can buy a lot of fuel for what a 4 stroke cost), what you have to watch for on those motors is the enrichner circut, they can leak fuel and make it burn even more

Re: First trip in the salt with the 250
 

I thought all outboards used excess fuel. If you look at an outboard when it's running you will usually see a stream of the excess fuel shooting out the side or back through what is commonly called the pee or piss hole but I believe that the correct term is "excess fuel letter outer" or something like that. Like Spare said this keeps the motor cool. A guy I know had his excess fuel letter outer stop working and sho' nuff his motor blowed up right after that. Those VX's must have two holes.

The excess fuel that most are accustomed to seeing come out of a 2-stroke is due to the inneficiency of a 2-stroke engine. Every time that a 2-stroke brings in air to the cylinder the exhaust port is also open at the same time. So some of the fuel-air mixture that was just drawn into the combustion chamber is lost through the exhaust, this is where most of the unburned fuel comes from. In the older cross-flow engine roughly 20-30% of the intake charge went out the exhaust unburnt. The newer looper's supposedly got this down to 8-15%.

In a direct comparison I have an 83 115 cross-flow engine and an 85 140 looper. The 115 burns roughly 11-12 GPH @ 4200, and my 140 with more HP burns about 8 GPH at the same RPM. And then you can compare a carb motor to an injected motor. The injected motor use's less fuel at idle since the fuel is injected under pressure which helps it atomize, where as a carb motor relies on vacuum from the engine to pull the fuel in and atomize it. Unfortunately 2 stroke's(espescially loopers) don't have very good vacuum at idle, so more fuel gets lost unburnt. And then you have the excess fuel for oiling reasons since the fuel actually carries the engines life-blood. And so on and so on.
