    No spark plug spark... 170 MC , 1985 Sea Ray

    bring the motor up to TDC on #1 cylinder (you need plug out to verify TDC and light up the timing mark) make sure the rotor is pointing to the same wire that is going to #1

    No spark plug spark... 170 MC , 1985 Sea Ray

    if your getting spark with an in-line tester at the coil, then the points, condenser and coil are working. the issue will lie with your coil wire to cap, wires to plugs, the cap itself or the rotor. the dwell meter will help you dial in the gap (dwell) prior to setting timing

    No spark plug spark... 170 MC , 1985 Sea Ray

    how are you checking spark? have you hooked up a dwell meter? a dwell meter will tell you immediately if you have a good gap and if the points are working. with points, if they sat for a while, they film up. which is why the service manual calls to file the points, rough gap them, verify the...

    No spark plug spark... 170 MC , 1985 Sea Ray

    no, if you are correct and there is spark being generated at the coil, then the culprit is your distributor cap, rotor or wires. with points, you MUST re-set timing after adjusting dwell.

    Hard starting

    sitting for a month, there will be no fuel in the carb, so it will need to crank a bit to get fuel to the fuel bowls. if you have an electric pump, you may not need to crank as much. on an omc, you pull the throttle handle out toward you. it will move about 3/8" outward. you grab the base...

    Hard starting

    how long is it sitting prior to firing it up? a vented carburetor will evaporate the fuel in the bowl over a period of 2-3 weeks. it may need to crank a bit to get fuel to the carb the only filter needed is the fuel/water filter, however as AD mentioned, it wont cause hard starting unless it...

    No spark plug spark... 170 MC , 1985 Sea Ray

    if you have spark at the coil butt not at the plugs, its either your plug wires, your distributor cap or rotor. and the rest it going to be working if you have no spark anywhere then the points are not opening and closing or your condenser is shorted. points are nothing more than a mechanical...

    ENGINE SWAP built 383 in and stock 454 out

    first, unlike a car, a boat bilge actually traps vapors, and using automotive accessories in a boat means you just built a bomb., marine stuff is designed to prevent fuel leaks and igniting of any leaks. lopey idle usually means lots of overlap, cam centerline on a marine engine is such that...

    How can I fix the water leaking at the stern for my boat?

    your boat has a 2.5 liter which puts the boat 1990 or older. fiberglass boats older than 15 years are on borrowed time. your boat is leaking because the transom and stringers are most likely rotten. this is the same as you having a broken back, broken arms and broken legs and expected to...
