Happiness is. . . . . .

I did a road trip on Saturday. Put 974 miles on the Magnum. Averaged 20.2 mpg, towing a small U-Haul trailer.

Keith finished my engine.

Should push the old Ski-Sporter along nicely.

CMI E-top headers should look pretty good too.

Yowza!

Looks great - hang on tight!

I was just thinking I could have named this thread, "Bill can't keep a secret."

But I find this kind of stuff interesting, and thought others might too. I never intended to make a super fast, stealth Ski-Sporter. I wanted to make a boat that could comfortably and easily cruise at 45 - 50 running about 3,500 rpms. With this engine making almost 315 hp, and 470 ft lbs of torque at 3,500 rpms, IF I can find enough prop, that should be very achievable.

Besides, if my goal were to make a super fast little boat, a 1967 Ski-Sporter most certainly isn't the boat I would have chosen to start with.

Matty, hopefully I can get the engine in the boat sometime this week (I had to order some additional parts), and can test out your props.

Nice, now get her done!!!!

[jl1962]

I can't keep a secret either, plus I always say good news travels fast - and your boat may travel faster than that - Congrats!

I wonder how a 26" Ultra would run on your boat?

I forget - what did you do about steering?

[Just Say N20]

I forget - what did you do about steering?

Nothing yet. I'm sure that at some point in the future hydraulic steering will become a reality. A little "wallet recovery" time is necessary at the moment.

[jl1962]

I may do something one day, but for now I've been reading Ralph Savarese's steering upgrade thread very closely.

Not sure if there is as much room in the back of a 16 as there is on an 18 - but I may take some measurements.

NICE

Bill, those fuel consumption numbers are very impressive.
Particularly in the 3400-3900 RPM range. And if they're real, in Diesel territory!

[Tony]

Bill, that is a very nice-looking engine!

Jay's Ski Sporter, formerly mine, has a tuned up SBF and was a real handful at wot. The "helmet slop" coupled with the chine walk made it quite exciting, to say the least!

The next time I get over to GR I'd love to take a gander at your impressive renovation. Now that I'm retired I ought to have plenty of time on my hands!

I didn't notice the gallons/hour column the first time. That adds some fun.

Let's see, if you can spin a 27, and get slip down near 11, you could make 55 mph at 3900. At 20 gph...2.75 mpg. That'd be pretty awesome for 55. Don't know if it's really possible, but it'd be very cool if it were.

[Just Say N20]

I didn't notice the gallons/hour column the first time.

That fuel burn rate is at WOT as the engine is pulling against the dyno up through the rpms. Just running at 3,000 rpms will not burn 19.xx gallons an hour.

Should be pretty efficient. Pending finding the right prop.

[MDonziM]

Bill,

Those dyno specs look great. Max torque under 4,000rpm is nice for your cruise expectations. Engine looks really nice too, I really like that crossover. I said it before, but it really warms my heart to see the time, effort and top notch results of your restoration. Now comes the fun part, get that motor in and start enjoying it.

Bill,
Excellent restoration the motor looks awesome. I’ll be watching very closely to see how the new mill fits in the 16 engine compartment. At your current pace you will complete well ahead of me. Also looking forward to seeing performance numbers and how the Holley and MSD work out.

The last column is lb/HP/hr and is the true indicator and gives about 17 GPH @ WOT.......if you were propped for that engine speed.

Anything under .5 lb/HP/hr is really good for gasoline.
