blower motor idle surge??bad thing??

[Unchained]

Thanks again for your input George.
I sent you a message on the V-drive boats site.
I need some expert advise on this monster. It goes from 30 to 80 in two or three seconds and it just keeps pulling harder.
I feel I need to optimise the prop location forward of the transom.
I want some more input about the sponson strakes you mentioned too.
I have a three blade Menkens 11" x 15 with a cup on the trailing edges.
I got it from a guy in Az who had it on a ski race Schiada. It seems to work OK. I tried a two blade 11.25 x 15 also. I didn't like the vibration at all.
It shook the screws out of the face of the oil pressure gauge.
The motor has no problem at all getting on top of either of those props.
I'm still using 32% gears.

Lost my surge over the winter, I was thinking my fuel might have went to shit.

Funny that you had the same experience....gauges failing with a two-blade.
Between us, we're learning something.
Two-blades don't want any engine monitoring.
Dan Chevillet (Skull Brothers Racing) told me that they used to remove the tach before taking the boat in to John Haas. Otherwise he'd remove it and throw it away.

An update on Mark's (Unchained) boat. He's currently suffering from some kind of modesty malady and might not post this.
He's still sorting things out, but he was taking people for rides the other day and gave a ride to a guy who runs about 120 mph, local king of lakeboats. This is what the guy had to say, posted on Screamandfly.com:
"I forgot to mention........
I was taken for a QUICK ride in Marks' new boat. Believe me, none of us are even close to being in his league. I'm just glad Mark backed off the throttle when he did, cuz I was just about ready to pull the bottom of his dash clean off. It may have only lasted 3 or 4 seconds, but it was the most hair raising, adrenaline pumping, not sure if it was pure excitement or just shy of being terrified experience I've ever had in a boat! IMPRESSIVE!!! Thanks for the ride Mark."

They still making solid lifters???:jawdrop:
Sorry...I didn't mean to confuse you. Most peeps know you either dealing with hydraulic roller or solid. Solid Roller Lifter
Maybe this will help:
I would be more worried about your Solid Roller Lifters than your bottom end. After the oil heats up you probably dont have much pressure at the bottom of the surge. If your running Solid Roller Lifters you might want to keep the r's up while your in gear in the no wake zones. I always keep 25 -30 lbs (oil) at idle in gear, no matter what. After a long, hard run it's tough to keep the oil psi up for your Solid Roller Lifters and not piss off dock owners.

The only thing better than one motor surging...
...is two (http://users.accesscomm.ca/tombrown/Labor Day HB 3.wmv).
Sounded like a model airplane engine

Thanks for dumbing that down
