    Water Pump Question - Alpha 1 w/Closed Cooling

    I have had similar situations and was able to route the water with some creative plumbing using some hard drawn copper pipe elbows sweated together from the hardware store. Glad Shawn could help he always came through for me and Marine Power are good people to deal with. I purchased quite a few...

    1978 Starcraft Holiday 18 I/O steering issue

    The exhaust housing he should have is more stream lined than the one with the screen. However the marks are just rear of the rear vertical mounting bolt and there is a oblong slot that the bolt is in for left to right adjustment. You can try loosening the 2 mounting bolts and moving the tab...

    Ballast resistor? why

    It appears from what you are describing you actually have a electric shift model not a 800. The resistor you are describing on the starter is actually a fuse. The epoxy is a sealant. There also should be one on the alternator. You can get what is called a fuseable link from NAPA in various...

    Couple of tips for reinstalling a Cobra drive....

    Good information and and really helpful Lou. When the Cobra first came out I re powered a customer’s boat. It took us about a half hour to finally get the drive mounted. The rear of the boot was holding the shaft back and we did not want to force the drive on since we were not familiar with...

    Water Pump Question - Alpha 1 w/Closed Cooling

    I set up my Donzi with the belt driven pump and through hull style connected the drive pump with a “Y” pipe and a sea lever ball valve. That way the drive stays cool and using a ear muff flush out, it is easy to run the engine on the trailer. I have seen transom mounted pick ups and I believe...

    1978 Starcraft Holiday 18 I/O steering issue

    Is the steering easy to turn in both directions when the boat is on the trailer In the full down position or in the water not running? If the steering is not binding then look at the marks on the rear of the exhaust outlet. There is 1 which is larger and usually is the best setting. If there...

    volvo AQ125B overheating while on plane

    Look at the aluminum nipple that feeds water to the transom plate via the rubber hose. It is easy to change with a Allen wrench and a screwdriver with some patience. The other thing if the problem persists will be the “O”ring that seals the lower gear housing to the suspension fork. Tilt...

    5.7 Volvo Penta Overheating at Idle

    Inside the thermostat housing there should be a small bypass port that that lets water circulate when the thermostat is closed. I have seen them to be either partially or completely plugged with corrosion causing a similar condition.

    5.7 Volvo Penta Overheating at Idle

    What year and model drive do you have? how long has this been happening? When the temperature goes to 220 on the gauge does it ever go back down if you just let it idle? Do like AD said about using a IR temperature sensor.

    Carbed Mercruiser 260 5.7L Missing Above 4000 RPMs

    This is something else to check with a flush out. Start the engine then put it in forward, turn off the engine and push the throttle as far as it will go. Go and look at the plate where the shift linkage is, look at the shift interrupter switch with the lever and plastic roller, the roller...

    OMC King Cobra won't engage forward gear, but reverse works good

    Have you checked the condition of the shift cable going through the transom. Sometimes the outer jacket separates and the cable will not give full stroke. The control box has to move the inner core of the cable 3” from forward to reverse.

    Water in oil...

    The thinnest part of the casting is usually at the bottom of the water jacket Inside of the crankcase. You might be able to get a fitted block which comes with main ,cam bearings & pistons with rings. You re use every thing else. Otherwise just get a marine short block. Marine Power in...

    What is this and where does it mount?

    If you need to get to the lines going to the trim block just remove the 2 1/4” 20 self locking nuts and pry the block down, the gasket may survive but if not you will have to either get a new one or “old school” make one.

    What is this and where does it mount?

    That is the Alpha style. Unless you already have the Alpha style large rams. Low pressure high volume. Which use larger diameter flexible hoses. You need the opposite which is what you currently have, high pressure low volume.
