    Mercruiser 5.7L engine with a 1.84 outdrive. Prop suggestions.

    Thanks for the reply. The whole outdrive unit seems to be working correctly, turns and engages forward and reverse properly. If I can get just the upper at a better price will do that. Thanks again.

    Mercruiser 5.7L engine with a 1.84 outdrive. Prop suggestions.

    1988 GW Invader 200ss. Dry weight 2400lbs. Boat started out with a 4.3L and a 1.84 outdrive. I bought it recently with a blown 5.0L but still has the 1.84 drive. A 14.25 x 20 3 blade prop was on the boat when I purchased it. Am going to install a 5.7L. Can I still use the 1.84 drive if propped...

    1988 Mercruiser 5.7 timing issue.

    Thanks for the responses... This is a marine engine. Engine does slow down and want to cut out, will also exhaust backfire intermittently. Will also emit some steam when hot and at higher rpms. Overheating because of the poor timing probably? Will give your suggestion a go.

    1988 Mercruiser 5.7 timing issue.

    Sorry for the delay. My main driver vehicle has issues and have been working on them so this went to the back burner. Will check the latest suggestions and post my findings ASAP. Thanks

    1988 Mercruiser 5.7 timing issue.

    Also, I pulled the exhaust manifold to make the piston stop test easier and the #1 cylinder port was wet and dark black. Did not smell like gas. 3, 5 and 7 all dry, looked normal. No water in manifold.

    1988 Mercruiser 5.7 timing issue.

    Did the piston stop test. Both measurements equal distance from factory damper groove so #1 cylinder is hitting tdc correctly I assume? Engine runs fine from idle to about 3000 rpms where dist. is currently set but will stall out and backfire when trying to go wot. Probably a different issue.

    This a 1988 engine, thunderbolt IV ignition. Thought grounding was only used on newer systems.

    1988 Mercruiser 5.7 timing issue.

    This is a different engine. Removed the 305 and installed a totally complete 350. I did not remove the distributor, only tried to adjust the timing. Also, this is a sterndrive. Thanks

    1988 Mercruiser 5.7 timing issue.

    Yes the engine ran before install. Did not touch the distributor before I checked the timing. I replaced a leaking oil pan gasket while it was out of the boat and must have taken out a bolt that I didn't need to because the oil pump came loose. Reinstalled pump with no issues. Good oil...

    1988 Mercruiser 5.7 timing issue.

    Just installed this engine. Coil, cap, rotor, plugs, wires all replaced. All plug wires connected to correct cylinders. Did not move the distributor. Starts OK, idles a little rough. Checked the timing and it is set to about 33 degrees {approx} BTDC at 750 RPM, warm engine. Try to rotate dist...
