Arneson Surface Drive Issues
I'm wondering if anyone else out there has had similar issues as I did converting I/O drives to arneson surface drives. I have an express cruiser Formula 370SS which is a bit heavier 16,000lbs and beam of 10'6" than your typical off shore boat. When I installed the drives over a year ago I couldn't get the boat up on plane. Most of the props made for that drive are at most 18" dia. I was getting too much prop spin or cavitation to push it up on plane. Then I had larger props custom built they were 22" diameter 6 blade 26 pitch. Now I have too much prop and the engines won't turn past 2000 rpm and still can't get up on plane. These props are super expensive as you know and this is a very tedious process. Is there another solution out there that I don't know about? Ric over at Arneson hasn't been any help. Thanks.

There's a guy on Boatfreaks who put a pair on a 47 Wellcraft Excalibur with good results. Maybe find out what he used. 22 inch sounds like way too much prop. How deep are your props at idle?

You will need a vent tube for your larger diameter propellers to break loose and get the naturally aspirated engines to rev. Bill @ Ateco is making these up he told me as I have been in contact with Bill along the way during this project.

That would be the case if it were true but I don't operate that way. Bill @ ATECO Engines handled the installation and I have been in contact with Bill on a VERY regular basis. Thanks for the confidence.

If you contact Rik...he will take care of you right away. Customer service has ALWAYS been Arneson's motto starting back when he was in the pool sweep business.
