    Trailer Tires

    Sounds like you’re getting there.... One other thing radials vs bias ply, the sidewall of a bias tire is the full thickness of the tread vs the thinner more flexible sidewalls of a radial tire. So if you have bad beat up ramps like my local one the bias tire will be more durable. The same...

    5.7 Volvo Penta Overheating at Idle

    It’s a cooler for the P/S system. The incoming seawater cools the P/S fluid. Most of these engines don’t have an engine oil cooler; this is why a heavier weight oil is recommended than what’s typical for auto use.

    5.7 Volvo Penta Overheating at Idle

    I’ve done it (Cobra is the same as the Volvo) on my boat there is an access panel that is above the back of the engine that comes off so you can get at it.

    Oil type

    Nope mine’s an OMC Cobra with dog clutch shifting so it really doesn’t matter which oil I use. With a cone clutch like Volvo uses it can matter so I’d use the VP gear oil...

    Oil type

    If I recall V/P used to recommend a syn straight 30, however this was difficult to find and later on they switched to a syn 10w/40. What most people seem to use is Chevron Delo or Shell Rotella 15w/40 or the Merc/Quicksilver 25/40.

    Oil type

    On these engines the main thing is to not use a low viscosity automotive oil like 5w/30 or 10/30. You can use straight weights like straight 30, or 40, a 20w/50 or you also can use the Mercruiser/Quicksilver 25/40 or the 15w/40 used in both diesel and gas engines. The idea is that marine engines...

    Condensate in manifolds?

    Certainly with the weather conditions in the northeast it’s possible just as you will find the engine covered with moisture on the outside when it’s humid and the temp drops to a level that causes moisture to condense out of the air. This is why engines that are not used in the off season should...

    Trailer Tires

    Honestly I'd get the Kenda Load Stars, I've been using them since 2004 and never even one flat or other failure. As I said I would not buy far eastern made radial trailer tires, I would buy the Goodyear Endurance but they are at a different price point. Low speed towing to the ramp/home/storage...

    Hydraulic trailer brake system overhaul

    A 24 foot boat towed by a Tacoma I’d say you for sure need trailer brakes that work. It’s your choice but if in salt water you would want disc brakes (stainless) but in fresh water you can use drum brakes if you prefer. I use galvanized drum surge brakes with zinc plated drums even in salt...

    Trailer Tires

    Tony I've been using Kenda Load Star bias tires and am on my third set, each set I get about 8 years from and never had a failure. I replace them when I start to small see cracks developing in between the treads. Same use as you, miminal trailering. I got them from easternmarine.com in...

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    When my original ESA went bad in 2015 I changed it out with a CDI unit which works perfect with the points; I’ve heard mixed things on the Petronix system but it’s nice to have an option. I grew up with cars with points though so changing them is not a big deal to me...

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    That's great! I'm wondering if Pertonix modified the electronics to make it plug and play.

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    So you're saying that you kept the original OMC ESA system and it works as designed with the Pertronix? Because in the past there was a wiring addition you had to add to make the ESA work using diodes, or you had to replace the ESA with one that will work with electronic igntion.

    Motor Knock

    An engine stethescope really helps with these kinds of problems. I had a similar issue when I did my top end overhaul (reman heads) 4 years ago. Heard a knocking noise that was intermittent. At the same time I had replaced the exhaust system, changing from the older OMC one piece V6 exhaust to...

    Valve Adjustment, 2004 3.0

    agreed the tricky part is determining zero lash. When I replaced the heads on my 4.3 I used the zero up and down on the pushrod method + 1 full turn. And got 160-165 compression numbers.

    1993 omc cobra doesn't want to crank

    Also, you might want to remove the spark plugs, make sure there isn't water in the cyls. That can mimic the problem you are seeing. ALWAYS check for water first, when you have a slow cranking problem preceded by "it just shut off"! If there is water in there you want it out fast and the cause...

    5.7 Volvo Penta Overheating at Idle

    I always use OEM impellers even though I usually have to order them for my OMC.

    1st Run of the Season

    Well I think mine learned that there are easier ways to have fun, lol. The boat I gave my son some years back when he was still in high school is a 10' Walker Bay with a 2012 Suzuki DF 2.5 outboard. He loves it! Low maintenance, simple, hose it out and all good. He takes me for rides in it when...
