Default Sailfish 2660 WAC ventilation issues.

Anyone out there who owns a Sailfish 2660 WAC w/ T-150 4stks had any ventilation issues with their boat. I have to run the motors trimmed all the way down, or they will ventilate. Nothing on the transom to obstuct water flow either. Any suggestions

Try lowering Your mtrs to the top hole. Sometimes the factory mts them in the second hole and You will experience cavitation.

What do you mean ventilate? Do you mean cavatate? The engines might be mounted to high.

Also, how do you know they are cavitation? The reason I ask is...When we took our boat out for the first couple of times, we kept on hearing a weird sucking noise that sounded like the motors were cavitation every time we hit a wave. We eventually learned that is was not the motors, but the over board drains creating a sucking noise every time the transom would go in and out of the water. It was almost like someone was turning a vacuum on and off.

I know they are cavitating becuase when the motors are trimmed just slightly up, the rpms jump 500 somtimes 1000 rpms. No sucking sound. Assuming you have the 2660 WAC, what hole are your motors mounted on first, second etc.

I remember this being an issue last year. Sailfish mounted the engines a little high. PM cpc23, he had the same issue and the dealer (K&K outboards) lowered the engines and that fixed the problem. Sailfish lowered the engines on the new 2660 WAC. I just recived mine and the engines were mounted lower.

I have heard of a few Sailfish owners using wedges behind the engine mounts and handling ventilation issues that way. I have a 2360 CC and do not get any ventilation issues to speak of. BTW Ventilation is when a prop is catching too much air while turning...Cavitation is actually when a pressure drop actually cause the boiling point of water to drop and the water turns to steam..

Exactly !

Ventilation or Blow Out occurs, when the prop looses grip.

Cavitation is some sort of Implosion , at the lee side of a blade and can damage or destroy the prop byeroding material off the blade.

My 2660 WAC is an 06' and the motors are mounted on the second hole from the top. Would this year or mounting height have to do with the ventilation issues?

Although I own a 2660 CC , I cannot comment on the WAC.

I would call Denny WarrenSales & Marketingat Sailfish Boats (229) 377-2125 or email DWarren@sailfishboats.com . He is a very helpful guy.
