    Gulf Coast Hull Strength / Boad Hull Strength

    Hi all, I was hoping I could find some answers from someone in the know. I recently bought a 20' Gulf Coast High Side. I was pressing on the hull near the bow and aft. It's not rock hard like my buds 18' Champion. From what I understand all these boats are foam filled. The Gulf Coast is a...

    Bogging problem Evinrude crossflow

    Hi all. I have been trying to figure out a what seems to be a fuel problem. This is an evinrude '73 V4 crossflow. I can get on plane, but after a few moments the engine dies down, as it's in need of fuel. Squeezing the primer bulb does nothing. Depressing the choke primer helps a little but...

    jetting chart

    Does ne1 have a jet chart for a later model V4 crossflow with the carbs that have 2 idle air jets, 1 air WOT jet, 2 mid fuel jets, and 2 main fuel jets? 1 3/8ths carbs, sorry, I don't have a part number. These carbs were also used on the v6 235's.<br /><br />thanks

I am guessing I have 120hp at the prop(73' 135 V4 rude(crossflow), it has been ported with square ports, forged pistons, stuffed crankcase, B.B. exhaust) it's on a 74 wellcraft 17" center console V-hull.

    Primer fittings

    I have a factory V4 140 intake manifold. I have no idea the year, but the primer solenoid connects to 4 fittings on the intake manifold. I took all 4 fittings out and sprayed cleaner/air through them. It seems that I can spray air through the back side and air comes out fast. But if I blow air...

    How much compression is too much?

    Does any of you veterans out there know the max compression that one can have with 87 octane and good TCW3 oil. Is there a "best" mixture to use with higher compression?

    Electric fuel Primer

    I am adding an electric fuel primer to my 1973 evinrude 115hp. Could someone tell me how it works? Does it have a restrictor so that it does not pump a boat load in the intake? Is it only 1 cylinder the fuel enters? I have a 140 intake that has the 1 port for the fuel primer on the intake. Does...
