    Electric boat maker shutters plant in WV

    With a stroke of the pen the inboard & I/o market was just about killed because certain regulators demanded over priced heat generators in your engine compartment that cost $5,000–$7,000 to replace so no one buys gas inboards or I/os here any more. I was at a Chapparal dealer on the south shore...

    Electric boat maker shutters plant in WV

    Yes That’s in anticipation of ever more strict regs. Don’t think they aren’t coming So in the EU for decades they have had diesel sterndrive both Merc & Volvo Given current tech it makes sense if you want some kind of decent range… Mid sized boats

    Electric boat maker shutters plant in WV

    That’s a damn sight better than what the greens will let you have in a few years. Ever wonder why so many people put up with sterndrives in the Med Sea salt water? They are all diesels! Because their fuel is so highly taxed!

    Diesel wouldn't have to run continuously, think of how regular gas/electric hybrids work. Diesel is more efficient in terms of fuel use than gas engines by a lot.

    The most sensible but not cheapest “green” marine propulsion would be diesel electric which is well proven but too expensive for mass market pleasure boats

    2004 3.0 Exhaust flapper question

    Yep that high idle is not good for a dog shift outdrive; I set my Cobra at 600 rpm in gear in the water & it goes in, and out of gear with 2 fingers

    VP 4.3 GL-B - Spark issue

    If you’re losing power in the I terminal of the switch the gauges should not be working because they are powered off of that terminal

    VP 4.3 GL-B - Spark issue

    I’d check the ignition switch positions to see if you are losing voltage…. B terminal, red wire, gets batt volts when batt switch is on I terminal, purple wire, gets batt voltage when you turn the ignition to on S terminal, yellow/red wire, gets battery voltage when you turn to start Sounds...

    Loud tapping noise when accelarating under load 3k rpm

    Time to pull the outdrive for a driveline inspection; actually in the vid I don’t think the drive is trimmed up high enough to make the ujoints noisy.

    Volvo Penta Cobra Gasket

    BTW Coat the mating surfaces between the drive and the pivot housing with marine grease like triple guard grease. It will keep the drive from corroding onto the pivot housing. This sometimes happens on these 94 & up units. I would also coat the inner & outer lip of the bellows & the bearing...

    Volvo Penta Cobra Gasket

    Normal. The OMC Cobra drives from 86-93 use that gasket, the Volvo design ones from 1994 & up do not, only that irregular shaped oring for the water passage.

    setting the timing on 1989 4.3 OMC

    I’d also check the propeller for damage & prop shaft for run out. That early 4.3 has an even fire crankshaft but that didn’t totally eliminate the vibs inherent in a 90* V6; these will have a vib you can feel at about 1500-1700 rpm that you can feel even in neutral. However this also depends on...

    Merc 260 fit in Winns 190 Horizon bay?

    Basically from what I can see with the marine units they have a gasket under the distributor cap & a steel screen in the vent on the bottom of the distributor body.

    Toyota/Lexus Timing Belt Change Thoughts

    If possible I’d see if you can remove the covers over the belt drive and see what the belt looks like. If there are any cracks or fraying I’d get it done. If not you can decide not to do it just yet. BTW we had twin cam 4 Cyl Toyotas back in the 80s & 90s and had the cam belts changed at 60,000...

    does volvo penta 4.3gl and merc 4.3 use same block

    Post up some pix. OMC Cobras from 1986-1993 were the dog clutch model and then in 1994 they (OMC) were bought out by Volvo and the design was changed to what is essentially the same as a Volvo SX. Which is what that boat you have likely has. If it’s the older OMC drive I wouldn’t change what you...

    Merc 260 fit in Winns 190 Horizon bay?

    Chinese HEI? I’d rather have an old Prestolite marine points distributor!

    does volvo penta 4.3gl and merc 4.3 use same block

    If you take a look at engine remanufacture websites you can see the engines they sell grouped by what variation they are of the series. The 4.3 went through many variations and the major ones were: 1985…2 piece main rear seal, flat tappet cam 1986…1 piece main real seal 1987-88 same as above but...

    does volvo penta 4.3gl and merc 4.3 use same block

    If the block was cracked the cyl heads are probably also. You need a GM/Chevrolet 4.3 of about the same time frame as that marine 4.3. As far as the engine itself it’s all GM. Only the added accessories to make it work in a boat are Merc or Volvo. What year is the boat it came out of? The only...

    does volvo penta 4.3gl and merc 4.3 use same block

    They are all GM/Chevrolet engines…. I’d remove the intake manifold to see if the block is cracked in the cam valley before spending any money on it…

    setting the timing on 1989 4.3 OMC

    https://www.streetmusclemag.com/tech-stories/uncovering-secrets-ignition-timing/ Ok there is a pic if you scroll down that shows you exactly what your timing tab looks like. It's the one with the engine block painted blue.
