    aluminum prop comparison

    need to see what RPM you are turning at WOT with the throttle lever mashed lugging a motor will not only kill it, it will burn more fuel. see the first sticky in the prop forum. have the answers to those 6 questions.

    Stalled and never started again

    even new points in a package need the contacts filed. a film of corrosion will cover the points from non-use and they simply wont fire. being a 3.0, rough gap at 0.016", set dwell to 32 degrees, set timing to 4 BTDC. if the dwell meter doesnt show a reading while cranking, go back to the points.

    Stalled and never started again

    first, welcome aboard second, its nearly never the coil third. explain how you set the points. most likely the initial issue was the points needed adjustment. did you file the points? did you set the rough gap? what was the dwell? what did you set the timing to?

    Engine, Carb or Prop? need suggestions or ideas please.

    Engine, Carb or Prop? need suggestions or ideas please.

    There is no 2-piece RMS button coupler for a stringer 800 that I have found , and the 1-piecs RMS pattern is different. The bolt circle on the 2 piece rear main seal crank is 3.58" while the 1 piece is 3.00" bolt circle The Ford pattern is close to the 1-piece.... however with one hole rotated...

    Engine, Carb or Prop? need suggestions or ideas please.

    how did you mate up a 4.3 to the stringer drive? only the 1985 4.3 has the right crank (2-piece RMS) to mate up to the OMC button coupling unless you had a button coupling custom made are you sure the motor is not the 3.8 liter? with your boat being a 1984, the 4.3 didnt exist yet. the 1985...

    this should be the connections for the VP half system (going off of memory from 2008). reach out to your local dealer with the engine serial number and they can get you the correct diagram.

    Aftermarket add on for changing room curtain Do you mean gas spring? If you have an outboard, there isn't any. If you have an IO, look at the old one for the part number, length and force Google tongue weight. Plenty there I wouldn't tow with a mooring cover, it will most likely blow up...

    Bayliner 175 to 170 conversion

    There have been several I/O to OB conversions on Iboats over the years. Very few completed, non were happy with the results unless they used a pod I agree to sell it and buy what you want. Even if you gave away your current boat, buying an OB boat will be less $ than a conversion
