    1997 Sea Ray SS - No Cockpit lights

    Anyone have any advice as to where to start looking for trouble shooting no cockpit lights on the above captioned boat? Lights were working at the beginning of the year, but stopped. Figured it was a bad bulb, but checked both back bulbs and they work fine. Definitely no power at the back...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    Trying to do some diagnosis before I break the engine engine down. The boat owner reports that there was "sea weed, and even a zebra muscle" in the fuel system. The only potential cause of the same seems to be from a failure of the fuel cooler. I don't see any other way for water/seaweed/a...

    What engine do i have?

    If someone swapped out your 2.5 for an older 2.5, you'll likely never figure out the year of the engine. That said, as Bondo mentioned, it really shouldn't matter.

    Water in cylinder after engine is shut off.

    I'm not familiar with 537, I typically use a quality thread sealer (Blue Monster 76009) and I have never had an issue. Seems like you have to have bad risers/manifolds, a thread sealant issue, a bad head gasket, a crack in the heads/block, or somehow you're getting water through the...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    I agree. I agree, but chose to ignore a discussion with AllDodge as to whether he was right or wrong regarding time, vs water causing the issue of phase separation, that juice wasn't worth the squeeze. Thanks for the information. I knew there was a period of time (after 1996) that fuel...

    Water in cylinder after engine is shut off.

    Who rebuilt the engine? Did they use proper sealant on the head bolts? Did you have the engine components checked for cracks, or the block too? Did you also replace the manifolds with new manifolds or used?

    454XL ECM Harness Fuse Trips

    Try the same advice... Swap the ECU, if it's not the ECU check the breaker itself. Look at the wiring to the breaker before replacing, but the good news is, those breakers are generally pretty cheap.

    1993 crusader 454 serial number 90526 timing

    FWIW, that has to be the worst way to time an EST. They're virtually impossible to time at idle. I generally time mine at 1200-1500, and check timing at 4k for full advance.

    802 xl engine problem

    The cause is not likely electrical related, in the sense that it is stemming from a bad wire, but you likely have a sensor or mechanical issue that is putting the ECU in "safe mode." The maddening thing about getting a scanning tool is, the early ECUs (MEFI1/2, long style that plugs in the...

    Transmission options for Crusader 454XLI marine engines

    Where are you located, and what transmissions do you have now? Do you also have a v-drive, or just a transmission? Borg Warner 72Cs or ZF transmissions are great.

    Crusader Blue Paint

    This is the best option, IMO: I had my local automotive paint supplier custom match a quart of single stage industrial enamel. The best option that I've found in a can that isn't made by crusader, is Rust Oleum "maui blue."...

    1997 28' SeaRay SS deck

    Boat has a soft spot on the foredeck, near the hatch area. Affected spot is around 36", L shaped. 1) Anyone have any luck repairing from the hatch area, without cutting the top or bottom? 2) Any have knowledge of SeaRays core material of the area? (I've heard balsa, but no advice as to...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    Yea, I'm aware of all of that. I just wasn't sure if the fuel system in a 2000 (gas tank and lines) could hold up to phase separated fuel. Any E10 fuel that gets more than approximately 2% water in it, will instantly phase separate, with Stabil or not. I didn't know if I'm looking at all new...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    Thanks, I do not suspect bad gas, but stranger things have happened. The current fuel filters look good. Fuel pressure is good, but both engines run like garbage. It will occasionally stall at idle, and won't run under a load at all (it'll run up to around 1500 rpm, and fall on its face)...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    On both tanks, simultaneously, getting plugged at the same time? Boat owner reports that the port tank fuel pump went bad due to contaminated fuel, and a plugged fuel pump inlet… claimed that it has seaweed and even a couple small zebra muscles stuck in the inlet. Could that be a sign that...

    Fuel Issue - 2000 Formula 31PC 454 MPI

    Boat has a bad fuel issue. Fuel was drained completely, re-filled with fresh fuel, new fuel pump, couple new fuel lines, and still won’t take gas from either of the two tanks. Seems to run well off of a Jack tank. Could the tanks themselves be bad, or is it likely limited to the fuel lines? I...

    Bravo 3 Propshaft Seal

    Thanks for the reply. I do boat in shallow water with a sandy bottom, and sometimes kick up sand. Generally at idle speed, looking for a spot to anchor. When I do kick up sand, it's brief, and very temporary. The seal may have been original and lasted the first 600 hours, and 27 years... I...

    Bravo 3 Propshaft Seal

    Got my boat out and replaced the (destroyed) propshaft seal. Once out of the water, it had gear lube pouring down the skeg. Replaced the prop shaft seal, and all is good... but, what causes the prop shaft seal failure? Is this just something that happens over time? Is it caused by a worn...
