    1998 4.3GL VP SX Slipping

    Use Volvo Synthetic 75W-90. I adjust my shift cable by putting it in neutral and adjusting the brass block so it drops into the mechanism easily. I've added small metal washers to the joints of the mechanism to take out the linkage slop.

    1995 Omc 302 replacement to 351 help

    Nice boat! :) I'm curious on this as well. I suspect you may need the ECM for the 5.8 to provide the correct fuel ratio, but am interested in what the experts here will say.

    Replacing Trim sender with after market

    I would connect the sender to your ship's wiring and see how the gauge responds as you rotate the sender. If the gauge responds normally, then with the drive down, install the sender in the position that shows drive down on the gauge.
