    Re: Chevy 5.7 Stuck inlet valve.

    ALL 4 stroke engines have some amount of "blowby" ( crank case breathing) which by standards, is "recycled" into the intake manifold, usually in thru the "flame arrestor"...Marine engines don't have...

    Re: AQ280-DP PT blockoff plate option?

    I had room for mufflers because Chriscraft used an extended housing that allowed the use of "bob tailed" , i.e.Chris manufactured, engines. For that matter any "Borg Warner" patterned engine, hence...

    Re: Water top #4. ?

    Since you are FWC, your engine has two distinct water systems. The block and heat exchanger are filled with an antifreeze mix, while the exhaust manifold ( I believe) has sea water in it ( after...

    Re: AQ280-DP PT blockoff plate option?

    Given stated corrosion issues with drive, make sure the "Seating" groove ( and opposite mating surface for the O-ring is in good shape. Normally O rings only need , at most some lube on...

    Re: Aquamatic Swap

    ...... just VERY gently...... You want to polish more than remove any material ( except any mushrooming)
    If they are banged up and or corroded... buy new.

    Re: AQ280-DP PT blockoff plate option?

    When I went thru huli with my exhaust I left the Y pipe attached to the transom shield but:
    1) Cut the "Y"s to about 3" long ( just a handy dimension)
    2) Sanded the IDs of the "Y" pipe stubs the...

    Re Hinge pins... On a used boat once, the pins had been driven by the P/O and were slightly peened over. After much creative language, I did the following:
    Disconnected the helmet and everything...

    Re: Aquamatic Swap

    I did that exact drive swap. As I recall it was uneventful. I did however, change the water inlet to thru hull with an external wedge/scoop strainer ( does not need cleaning). This...

    Re: Carby flooding

    The blockages I've seen are not in the block per se, but rather in the two thin brass tubes staked into the venturi that suck gas up into it. You may not want to do this, but the test I use is...

    Re: Carby flooding

    My TKS on a 5.7L on a regular basis ( every 3 to 4 seasons) suddenly develops a total refusal to run under 1500 RPM. In every case the problem was an obstruction in the jet in the venturi. No...
  14. Re: can the 280 be fitted to work on the drive pictured (290)?

    I don't think that is the question the OP asked. I think he wants to install a complete 280 drive on the 290 transom shield/brackets.

    Re: Cold oil filter, Crusader 270

    Some oil filters have a bypass valve to allow flow when the filter is plugged. This valve also functions as side effect as a one way check valve. Soooo.... oil flow thru these filters is one way.
  17. Re: Is running outdrive in the full tilted up position any difference than turning it all the way?

    Depends on the drive.... 200 series drives have a drive lift system the is not designed to tolerate/absorb engine thrust, i.e.not an issue unless you are trying to propel the boat with the drive up.

    As a comparison.... I' ve engined and am restoring a 1969 Chriscraft Lancer. This boat was built with hollow fiberglass stringers, which is a feature today only in top quality boats. The boat has...

  20. Re: 1987 Bayliner 28 350 260 hp will not plane

    My guess is that after all is said and done, you will find that the boat is (was) overpropped in a futile attempt of a previous owner to get more speed out of the boat by installing a bigger pitch...
