    Engine oil difference

    You did not say what engine you have..... Very important for troubleshooting. I have been swapping between Merc Premium and Merc Premium Plus. Neither smokes much for me. If you have the EFI engine, I would suspect you might have sticking or leaking injectors. Possibly pressure regulator is...

    Compression test? 240 EFI Mercury M2 GEN. 1.

    You can try, but unless you have a flow bench and are experienced repairing Keihin injectors, I don't think you will have much success. It was well worth the expense. My engine almost always starts in under 5 seconds. Very little smoke.

    Compression test? 240 EFI Mercury M2 GEN. 1.

    Use extreme caution! Turn on bilge blower. Connect a good battery charger. Remove all the spark plugs. Key off! Advance throttle to full WOT. Connect gauge to your favorite spark plug hole. Use a mechanic test switch, connect to red battery cable and small terminal on the starter solenoid...

    wake board tower for 2002 Sea doo Challenger?

    I have a 2001 Chal. 2000. I found my tower new on ebay for $950. But that was about 10 years ago. I always wished I had been able to get the OEM tower for Chal. X20.

    Sea doo Challenger 2000 240 EFI gen 1 bogging down.

    But you did not say if test was done at Wide Open Throttle. Your numbers are low--- trying to figure out why. Idle is high for being in the water. Take a close look at the link to the oil pump. Is it correct? Is it holding the throttle open slightly?

    Sea doo Challenger 2000 240 EFI gen 1 bogging down.

    Who hasn't picked up a rope on the shaft? Those that have and those that will. 2 for me. A thought on this problem-- Could the stroke/metering link be on the wrong side of center? That is -- full oil at idle and minimal oil at WOT. Backwards. Causing overheat and bogging. If still running...

    TPS test with Digital multimeter

    208mV = 0.208V. If you don't show voltage @ WOT, bad news- time to BOAT. Just saw NIB unit on ebay for $592. Just to be sure- do both resistance tests. SMOOTH transition. This test is actually easier with an old style analog (needle) meter.

    What do I need to know before buying a 2003 utopia 205 with 240 Merc

    Check the rubber bellows on the steering and shift cable ends at the steering nozzle. The should be soft, flexible and intact. No cracks. Cracks will let water enter the cable and make it rust and fail. Neither is too difficult or expensive to replace, but could be a negotiating point.

    TPS test with Digital multimeter

    Assuming you have the 240 EFI engine- There are several threads here about the infamous, crazy stupid expensive Merc TPS. I wrote some of them. Let's back up a bit. How are you connecting to the tps? There is a VOLTAGE SETTING procedure and a RESISTANCE TEST procedure. For the voltage set...

    Stalling while out on water

    You did not say what engine you have- I think there were 3 different engines used. If you are getting 49 mph, it sounds like the engine is mechanically OK. If you have the 240 EFI, here is something for you to check. On the injector pump (Merc calls it the vapor separator tank vst), port side...

    2003 Utopia Jet Drive Ring Repair and Impeller Replacement

    There are several threads here about repairing wear rings. Some use JB, I have used lightweight fiberglass cloth and epoxy resin. Been in service about 5 years since. Just remember to make sure the water holes in the bore are clear after repair. Almost any repair will cost less than...

    Merc 240 efi won't re-start

    I did the old style tps swap about 4 years ago and still works well. The old pn was 14851T. Good luck finding one. I paid $125. 2 of 3 wires match color, 3rd is connected to the other odd color. Fitment & adjusting is to the book. Who paid $60 for test harness? I found it for $25 new...
