CLE Nose cone

[25ss]

Im sure this has been asked but i have a Carlson IO with an alpha doing
77 and was wondering if a CLE cone would do any good.

I doubt if you would gain, probably lose MPH. A nose cone really only helps when the lower unit is in a surfacing position. Your lower unit will always be submerged on that rig so I would say NO. Can you check your speed with a GPS, maybe on your phone. That speed seems really high!

Best wishes, Carter Powell

Carter thanks thats about what it thought.
On the speed that is gps actually i was out late this evening with some cooler air and saw 78.
Its a 20 ft glastron carlson intimidator that has a slightly higher x height.

you must have a lot of horsepower. s/b chevy?

[25ss]

Yes a built 383
I bought it with no engine put the stroker engine in it .
Had trouble finding a prop it liked found a 24 trophy plus that it liked.
Carried the boat great with very little trim and accelerated like an outboard but a little high RPM
Found a 26 trophy plus and now not as fast out the hole but still runs great and 5 MPH top end.
Trying to get 80 thats why asking about the nose cone

The CLE has a point and when trimmed out it will push the stern down. Years ago Hydromotive made a cone that offered less down force; It was more of a wedge. If your leaning toward trying something research that.

Not listed on their site anymore. Oh well. Sorry that isn't much help

What’s the blowout speed for the stock CLE case? Iirc the non blowout ring cases were a bit dangerous

You may want to consider the 1:32 gears that the Alpha 1 had when put behind the 454 Magnum 330hp. This ratio handles the torque better.

I take it the 1.32 gears overdrive the propshaft allowing lower pitch props
to ease the strain on the upper gear set and the case.
