    4.3GL blowing milky oil out the breather

    I guess I screwed the pooch when I winterized in the fall. After putting her back in this spring, I took her for a run and she was running terrible. I stopped, opened up the hatch and low and behold, there was milky oil all over the port side of the engine, exhaust and intake manifold. I pulled...

    Thanks IBoats!!!

    My water pump in my 4.3GL was peeing water on the weekend. Thanks to a few of our members, I was able to pull the pump off and replace the seal. It did not leak a drop until this past weekend, I have been water testing it for other issues which are resolved. So, a $4 oil seal and a couple...

    4.3GLPFS does not reach max RPM

    After the issues I had previously (bad rotor causing no start) and popping at WOT (new cap and rotor, new rotor failed-and it was original VP) the boat ran great. Today, I splashed it to give it a shakedown, at idle, it ran a bit rough and did not sound right. Went for a cruise around the lake...

    4.3gl pefs cranking but not firing

    Yesterday the boat ran like a top. Today after the storm I cranked it over but it did not even try to fire, it cranked and cranked. I pulled a couple plugs to check for spark, it was there. I pulled the fuel line off the carb and turned it over and fuel came out. Checked the safety switch, beeps...

    4.3gl pefs backfiring and popping under load

    So my trusty 2001 4.3gl pefs has decided to run lousy. It backfires and pops under load and has no power. I have checked the accelerator pump and it squirts a healthy amount of fuel down the throat of the 2bbl Holley. My thoughts are bad gas or the carb has issues. I pulled off the fuel filter...

    4.3GL PEFS won't come up to Operating Temp - UPDATE

    I finally had an hour up at the dock to take a look at the thermostat housing so see if there was any blockages. Sure enough, the bypass passage had 2 pieces of old impeller stuck fast in it. It took me a whole 2 minutes to remove the housing and a half hour poking and prodding the 2 bits out...

    SX-M Shift Cable Seals

    When I removed the shift cable from my drive, I made the mistake of not noting how the 2 seals (1small and 1larger) went on. How do they go on?? Does the small one go on the inside or outside and the same with the bigger one and how do they go on??

    Wrong Bloody Anodes!!

    After pulling off my drive yesterday and sanding down all of the corrosion, I replaced the anodes with Magnesium ones. The ones that were on there were deteriorated but weighed a heck of a lot more than the new ones which leads me to believe that they were either Zinc or Aluminum. I'm pretty...

    New Anodes and Temp Sender

    Since my SX is corroded pretty bad and I am in the midst of sanding and refinishing it, I ordered new Magnesium Anodes for it since the current ones don't look so hot. Also, I ordered a new temp sender, I figure it's easier to get everything done before the boat hits the water because once it's...

    4.3GL PEFS Temp Question

    Now that I have the engine running, I did some maintenance, new plugs, cap and rotor and I also replaced the thermostat since the operating temp never went above 120deg. The guage was replaced last year (a combination tach, temp, trim) and the problem existed before. I went with an original VP...

    4.3GL No Start

    Well, I went up north and picked up the boat today and when I got it on the driveway, I figured I'd try to start her up.On the way home, I filled up the fuel tank. So, I turned the key to the on position, went and got the muffs and hose and hooked them up (figured I'd give the fuel pump a chance...

    Picked Up a 4 Blade

    I was at the Toronto Sportsmen's Show over the weekend and ended up picking up a Turning Point 21p 4 blade prop for my 19ft fish'n ski. I found that with a 23p 3 blade, it would plane out real slow when loaded but cruised at a higher speed for 2900-3000rpm by 3-4mph. The 21p 3 blade would plane...

    I'm Going to Tackle Winterization Myself This Year

    So, I decided to winterize/service my boat this year myself with the help of a friend who is former marine mechanic and has his VP ticket. By the time I buy an oil pump and all the necessary supplies (engine oil, oil filter, fuel filter, synthetic gear lube) I figure I'll save around $200 or so...

    2001 VP GL Diesels after Good Run

    Hello, my 2001 Larson 190 SEI with a VP GL and SX outdrive diesels after a good run. It has the Holley 2barrel carb on it. It idles nicely and I am wondering if an 1/8 of a turn clockwise (lean) on each side would help out. If I turn the mixture screws that much, it does not affect idle quality...

    2001 Larson Fuel Leak

    I've got a 2001 Larson 190 Fish 'N Ski. Whenever I fill up with fuel, I get fuel in the bilge wheich usually means Leatting the boat air out for a day or so for the gas to evaporate. I was tinkering last night and found that the fuel is leaking from the top of the tank where the sending unit is...

    2004 Larson 180 4.3 Merc Completely Dead

    Here's the problem: Cruising along last night, the boat went completely dead from cruising on plane. There is no power to anything, none of the electronics work, it does not turn over, nothing whatsoever. We tried to reset the main circuit breaker (50amp) to no avail. The battery voltage shows...
