Vegas Deuce Strut Depth w/ Y535 Prop?

[ChrisCapaldi]

What would be a good starting point to set the strut on a Vegas Deuce running a Y535 prop?

Thanks,

Chris

Chris normally the strut is set where it should be from factory maybe if Alden comes on or Jerry Dunlap they can give you better way to set it up, my wifes running the super vee so set up is different Robert

Really don't have the boat dialed in yet, but right now it is set at 3/4" from bottom of hull to center of stuffing tube where it goes into the strut. Factory, it comes much deeper than this.

3/4" is a great starting point.

I have lenghtened the slot about 1/4" more so I can run even higher.

I run the Grimracer prop and it works very well.

Great boat and engine.

Thanks guys...I have been finding the boat can't pull the prop with the stock strut setting so I knew I needed to go up...just wasn't sure how high to go for starters.

The st produces alot of rpm,,, but lacks in the torque department imho...you need that thing to spin as free as possible without breaking loose...first thing is check your rudder input after a pass,,, if ita not centered when the boat is going straight,,,you need to square up the turn fin.. I would take and jam the strut to the bolt,,,if you wanna go higher cut the slot...loosen the two rudder screws on the rudder bracket and pull the bottom of the blade away from the transom,,(adding positive)....this helps to lift the transom slightly.... loose is fast,,,and thats the way i like em...i went back to the modified aquas after a season of the st...

The engine has low compression compared to other engines I have measured.

Low compression would (in my opinion) be good for RPM, bad for power. But, I think this engine has too low of compression. We found that we needed to remove one of the two shims (both are the same thickness on our engine) to get the engine to be able to spin the prop. We have not tried removing the other shim yet to see if we get more speed or not.

Without removing any shims, best we could do was get the boat to go on pipe at times, then come back off. Almost like running too lean, having too short of a pipe, or too large of a prop. Any HSN adjustment was no help (got it to the point where any more, or less fuel slowed the boat down)... Removing the shim helped a bunch.

What percentage nitro you using?

 

[SayMikey]

We jack the strut to the top even file an extra 1/8 in the slot. The GR prop works great

 

[Sean Bowf]

What percentage nitro you using?

40 and 45.

I am running 30% O'Donnell. Which Grim Racer prop are you using?

Chris

 

[SayMikey]

36x55 lose some toungue 50% nitro

 

[Grimracer]

Mikey does indeed know what the skinny is..

Grim

 

[ChrisCapaldi]

That's definitely more nitro than I figured I could run...I'll give it a try...do you run the head shim in with that much?

Thanks,

Chris

 

[TimothyJones]

I use 50% and its a stock out of the box supertigre.

I run ODonnell 50% and have the Grim Prop. Waiting for the grimracer 50% B)

 

[SayMikey]

Stock motor shims and all

 

[griz2575]

Stock motor shims and all

I only have one shim in mine and run the ODonnell 88 plug

 

[Grimracer]

Both shims, OD-9 and Grimracer 50% for me..
