    Do waverunners have low oil pressure shutoff system?

    No owners manual. He is currently changing the oil, as it is time. Unfortunately, the guy driving it at the time of the stall did not mention an alarm. I do not know where the oil leak was. The oil filter was very rusted, but I did not see any oil stains on it. The gasket on the oil filter...

    No Spark after Stator Replacement

    Is the new CDI stator compatible with the OEM switchboxes? Also, the OEM switchboxes needed particular stator wires and trigger wires. These were banded together to keep them connected to the same switchbox. Does the CDI module have anything like that? According to my '93 Merc V6 wiring...

    Mercontrol Wiring to 1978 Mercury 500 Thunderbolt

    Usually the engine wiring harnesses are too far gone to reinsulate them, as the conductor lasts longer that the insulation, but not forever. Also, check the quick disconnect plug. Wires like to break inside them.

    Older Mercury 8 Hp outboard

    A serial number will get you the parts list on the crowleymarine site. Some small Mercs are made by different manufacturers, so if you do not find the parts you need, you might look into that possibility. ie I had a camping generator made by Homelite. Parts were real hard to find. It turned...

    Merc 350 bolt v 2 barrel carb fluctuating RPMS

    The classic reason for rpm fluctuation is an air leak into the intake manifold. In your case however, that doesn't sound like an air leak into the manifold. It also does not sound like fuel supply issues or anything else I am familiar with. Maybe the carb bowl is overflowing and the motor is...

    Do waverunners have low oil pressure shutoff system?

    My neighbor has a 2001 WR. It stalled and was towed in. It looks like it has minimal motor oil in the block. Would the low oil pressure caused the engine to stall as a safety measure?

    Mercontrol Wiring to 1978 Mercury 500 Thunderbolt

    Replacement of the engine harness is usually a good idea at this age of th wiring. Wiring harnesses should be avail on the web. Try surplusunlimited. Check the boat side of the wiring as well. Those harnesses are also avail, but more costly.

    Mercury 2-Stroke Oils

    You should check your owners manual, but if memory serves, Optimax can use regular TCW-3 oil, in addition to DFI oil. Oil should never separate or get clumps. Dump that stuff.

    Fuel Tank incorrectly labelled?

    Gee, the tank is likely labeled right, IMO. A lot of things come into the amount of fuel that can be drawn out of a fuel tank. Most replacement fuel gauges are universal. They can be real inaccurate in judging fuel level. Fuel pickups can be the wrong length. Too long and they suck water...

    82 50 hp tilt and trim

    Well, the trim limit switch was on the starboard trim bracket of my '77 Merc PTT. The two PTT Trim Limit switch wires went to the main wiring harness, in the boat.

    No black/yellow kill wire on 9.9. 4-stroke

    Kill switches are not usually wired to solenoids. I would trace youe spark plug wires back to the coils, and then trace the coil wires back to the source of the spark. The kill switch will be wired to the coils or the source of the power to the coils, maybe even under the flywheel.

    1998 Johnson J115ELECM idle adjustment help!

    Your timing specs are correct. I believe Quickstart advances the idle timing. If you disconnect the 2 wire sensor on the cylinder head, Quickstart should be disabled.

    Gas guage

    Depending on fuel gauges to be accurate is tough. My speedboat has been thru 4 or so fuel tank gauges and the equiv fuel gauges changed over the last 45 years. It has a 8" tall tank. So, when the gauge reads empty, there is still 6 gallons left. !/4 tank is 9 gal, full tank is 18 gal. Each...

    Prop change on my bowrider

    Solas is a good prop IMO. I think Turning Point Hustlers are better. I think the TP Hustler has more rake, which helps a high speed boat, but is also useful with a std powerplant, like you have. Just an opinion

    options for boat cover supports

    Covers stretch. We need to support them no matter what.

    1998 Johnson J115ELECM idle adjustment help!

    My Johnnyrude Service manual covers your motor. The initial idle mixture setting is spec'd at 5-3/4 turns open. Make sure the motor warms up and the QuickStart system disconnects as that will increase idle RPM to 1200 or so.
