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. |

A friend had a 34' PQ that also has the 2 large steps. His drives had spacers on it when he bought it. Possibly for this very reason?
can you think of a reason why your friends were reversed? |

Level the drive with the bottom of the boat and mark your trim indicator with a piece of colored tape.

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?? |

like on reply#32 the bravo drives come with a spacer,the only difference is the location of the spaces,front or behind the ram bolt, on bravo 1 the spacer is located in front and on bravo 3 the spacer is behind,mine where reversed,wont know if thats my problem until I go out again.
can you think of a reason why your friends were reversed? 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. |

Just so I do this right,
