To make it simple, was there anything wrong with the old boots?Darn. Is there a recommended non resistor plug I can swap these out with then? Or should I keep the plugs and find some different boots
Great info, see us old timers can learn something too.OEM Spark plug boot part number for you SD is #278000237 wich will show up to be a NGK TB05EM part, a resistor-type boot. Spark plugs are ALSO resistor-type BR8ES NGK. Resistor boot AND resistor spark-plug setups are not that common but that's the factory setup. Would strongly advise against using either a non-resistor plug or boot on any Seadoo. (But if you insist on doing it, please tell us how it went).
It controls spark advance and whatnot but it gets the clue on when to fire the spark plugs from the trigger coil (a far simpler and cheaper component that you should be testing)The MPEM box controls spark right?
That's great news!!I checked the trigger coil and it’s good. After I plugged that 6 pin plug back in I tried to fire it up just to see what would happen. Guess what? It fired right up. Maybe the plug just had some corrosion on the pins or a slightly bad connection.
Anyways, now onto replacing the fuel lines. Thank you for all the help! I might need more before I’m done![]()
I've investigating just that: The ideal fuel line is supposed to be a marine-type, "SAE J1527". There are a few sub-types, A1 to A15. Even from the most Basic A1 sub-type these claim to to have a considerably lesser "permeation" rate compared to, lets say an automotive carb spec "SAE J30R6" wich is good since bilges are usually much less ventilated than car underbodies. Also they claim theese will not collapse under the significant sucction from outboard fuel pumps, wheres the automotive fuel injection type "SAE J30R7" is more tailored for a high (positive) pressure fuel pump.So what is the recommended fuel lines for these? I can probably find a thread about it.
