    5.0gi TBI to Carb

    Michigan Motorz sells the set up you’d need for a carb conversion (pump, bracket & oil pressure switch). I’d want to see how the original ignition system is connected to the ECM and then figure out how to wire around that…might be able to eliminate the ECM entirely.

    First time winterizing my boat myself.

    Always better to change oil; if by chance there’s any water in either you want to know that now so that it can be dealt with over the off season. In addition while most people wouldn’t bother I think that doing an oil analysis on the motor oil is a good idea. It will tell you if cooling water is...

    First time winterizing 4.3 mercruiser, alpha one.

    The problem with the suck AF up the drive method is that most people don’t understand how raw water cooling works. The system has excess capacity and to keep the engine warm enough the thermostat functions as a gate valve. It only opens as needed to keep the engine temp close to the temp rating...

    Changing the ignition on an 1989 4.3 liter omc Cobra from points to Delco EST Ignition

    You need to contact CDI electronics & buy an ESA module that will work with the Delco EST ignition system.

    5.0gi TBI to Carb

    I’m not sure about the wiring set up on the Volvo but I think if you can study the schematic you might be able to figure it out. If someone has one to post up then we can make suggestions

    350 MAG winterizing - which method is correct?

    Yep that's what worries me. I'll use the 5 gallon bucket under the garboard drain, if it comes close to filling it, fine, if not then I hope we can reach the drains on the block on this boat. Merc really should have alternate instructions on what to do if the damn thing clogs up! The old style...

    Polishing or paint

    I’d try to restore the gel if you can, painting is expensive and may not be as durable as gel depending on what paint is used. That said I had mine painted in Imron ten years ago and it still looks great.

    4.3 Mercruiser ignition control module Thunderbolt IV

    If firing order is off the engine could be fighting itself

    350 MAG winterizing - which method is correct?

    These systems might work on an aluminum block engine but on cast iron it’s risky because of how cast iron corrodes; it flakes off and those flakes clog up those single drain systems. Maybe in fresh water that’s not corrosive but in salt…risky. Going to winterize my brothers boat with the Merc...

    350 MAG winterizing - which method is correct?

    That looks like some kind of single point drain system…follow the hoses & see where they terminate. Is there a valve or cap on the end? If so the one thing that you want to watch for is how much water actually drains from each one. The block should hold 2 1/2–31/2 gallons each manifold about 1/2...

    Mercruiser 5.0 crankshaft front oil seal replacement

    While the old style tin parts can rust through I think they’re better than plastic! Just spray the timing chain cover & oil pan once a year with Corrosion X. Worked for me 20+ years in salt water!

    5.7 Automotive Intake manifold

    You can find cast iron used intakes (won't find new for a '94, that should be a pre-vortec 12 bolt unit) on ebay, I found a nice spare for my old pre-vortec 4.3 that way. If you meant that you have a closed cooling system, then yes you could use an aluminum automotive intake, the corrosion...

    Has anyone built a boat with Marine Plywood

    There's a guy on the hull truth forum who built a Toleman, check it out, beautiful boat, a tree fell on it in a storm and he was able to repair it himself.

    yamaha fourstroke crank bearings

    You get the idea that they don't want anyone rebuilding them, but shops that sell remans, must get those parts from somewhere!

    Winterizing time!

    Perhaps Scott can say, I don't have any OMC Stringer experience, only on the Cobra which is more like a Mercrusier.
