Nice performance, So late in the week you will have much cooler air to run in. It would be interesting to see what some power air will give you.

[jjmalkow]

Absolutely awesome!! Love following your progress!

[Mr. Demeanor]

Went out after dark and took a look at my piston tops. It doesnt look too fat. Im going to leave it jetted where it is for awhile and pull a head after I get a good wash.
Thanks for the nice comments

It was pretty good today. 73 and low humidity. Im sure 40 degrees and no cross wind would do a little better. I may drop it in the salt later this week. Prop slip will be a tiny bit lower in the salt.

Way cool chris.! Great job.
Now leave it alone and lets do some boating.!

Let me know when, I'd like to see if I can break 100.....finally.

[Mr. Demeanor]

You have a 100mph+ boat. Its just not finished....
You need to write out a check list and go through it.

Absolutely. Looking forward to the upcoming runs.

The boat ran 92.7 right off the trailer today. Ran 92.5 the other direction. Dropped one size in jets and it picked up in the midrange but ran 92.7. It was crazy consistent.
At the end of the day the wind laid down a little and it went 93.9 with no other changes. Amazing what a little change in conditions can do. It wasnt a little spike either. It held 93.8+ for at least a half mile.
The prop is 1/2" larger diameter than what I have been running. I was going to try going up 1/4" which is about 1 to 1.5mph but I didnt have my 3/4" wrench. I dont know how the prop will like going higher but I would like to try it once.

I'll bet you know what the first on the list is.

My buddys ski racer ran 103 with a 175 efi on 87 octane. You should be 110 with a top end setup. Nice looking boat too

He will get there. Its just not set up and has real conservative static trim right now. It did like this 32x15 ET though.

[Mr. Demeanor]

Huh?

[Alan Power]

Working on a lightweight cowl for the yam V4! Should be ready in next few weeks!
looking at it I'd say it'll fit over a V6 too but will need to see after its finished!
styled on the SHO cowl.
Will fit stock tray and hopefully use stock latches!
