    Fresh Air Intake Vents & Glove Box Drain Tube

    I think those ducts are likely fine they are forcing air under the floor to fuel tank and engine compartment. I suspect on the rear of the boat or engine cover you have exhaust or other vents that pull air out probably higher up this cycles the air that could have gas vapors (heavier than air)...

    Might be worth getting a service manual and getting any PM done as it sounds like it may not have been serviced much

    Should you buy 20 year old boat to fix up or 10 year old boat?

    Top speed

    Depending on which prop and pitch that's on it, how much load is in it and exactly which 5.7 ( carb or mpi is about 40-50 hp diff) would expect top speed to be in the 45-50 mph range

    First post, new (to me) boat, and how badly did I screw up?

    When you do the impeller I would pull the drive check gimbal bearing and U joints and look for water in bellows. You should be able to jam a water hose in where the outdrive mounts in the water passage or take the water in hose from drive off and rig up a from to to the hose. You just want to...

    mercruiser 7.4 mpi can't figure out the ratio

    If you want to find out what was there originally I would contact Wellcraft, they order the power packages and the set up determination. in the parts book for my Sea Ray it outlined all 4 engine options with outdrive ratios and riser configuration.

    Gimbal Bearing Compatibility and Source?

    no he is saying you have too much grease on the tool and coupler, thats why drive shaft wouldn’t go in. I think autocorrect or Fosters correct messed up his post.

    Prop ventilation?

    Only other thing you may want to rule out is the prop hub slipping. I assume you have an older pressed in rubber hub, these eventually fail and need to be rehubbed.

    Is it worth it?

    I converted a 65 gto to electronic ignition made an unbelievable difference on easy of starting and drivability would recommend it highly. As per previous post well maintained points are just as good as any ignition system electronic kits makes life easier

    Mercruiser, 4.3L, Alpha One,175 HP, rebuilt in 2018/inboard/outboard

    Mercruiser, 4.3L, Alpha One,175 HP, rebuilt in 2018/inboard/outboard

    Absolutely its sellable unless. It may be less saleable if it is a 3.7 or inline six or really ancient. If in good shape try CL list complete drivetrain but you have to take the boat ... or list it higher if they leave what they dont want....
