So the two long vertical tubes I saw on the drives on the 42 Fountain at Cleveland were the blow off vents? They sat directly above the props and just looked like to tubes that went vertical and would stick out the water. The sales guy said they were to venitlate the props. But he made it sound like they provided air to the props so that the motors could get them rev'd up.

[QUOTE=4mulafastech;2831045]The reason is if the drives are tucked 'too' far at speed in a hard turn, it is more likely to spin-out/roll a twin stepped hull due to the added stern lift. I never have my drives tucked all the way in when turning (rule #1 of driving a stepped hull). QUOTE]
The drives should not be trimmed below level when turning at speed...period.

[QUOTE=omerta one;2831857]
great info thanks!
how do you find the neutral position on the outdrives on a boat?
do you start by leveling the boat trailer and then level the outdrive cavitation plate??

the boat has a pad,do I take a long 2x4 or level and have 3 to 4 feet against the pad and level that to the cavitation plate on the outdrives?
and on turns never trim lower then that neutral position??

No, I wasn't clear. The spacers were between the upper and lower housings, to put the prop in deeper. I think they were only 1" spacers. He never had any blowing out like you are experincing, so I'd have to assume the 1" spacers did the trick.

Do not trim below that when turning at speed.
