    Perkins 215c sea water pump failure

    Probably a bad shaft. If alignment was bad the seals and bearings usually go first.

    Chrysler Crowns

    I had Crowns many years ago. They had 6v coil with a resister for 12v supply. The coil gets hot because w/o the resister you're running a 6v coil on 12v. They can get hot enough to explode. I had that happen in a WWII jeep. The points are hot for the same reason. I'd buy 2 new coils and...

    life of a 671tIb

    High horsepower 671 Detroits usually go 3-5000 hours between overhauls. It depends on the maintenance and the guy driving them. I have got as much as 11,000 hours and always 7,000+. But I watch the exhaust gas temperatures and keep my oil clean. Party boats with hot dog drivers get as low as...

    increase alternator cooling

    Diesels run better hot than cooler. Most do best about 210° but most OEMs use a lower thermostat for warranty reasons. They also run better when intake air is cooler than 180°. I'd start with better ventilation. If you wan a common alternator with higher output, use a GM CS144, I do. They peak...

    Perkins T6.354 counter rotating water pump question

    The coolant pump can be rebuilt. Most require the pulley to be pressed off. The pump probably has a bronze bushing for a bearing and a seal. Both can be bought from a good bearing supply. I rebuild all my pumps. http://www.waterpumpman.com/ should be able to rebuild the pump.

    Weatherproof Fabric Adhesive?

    Flexible epoxy works best. There is no such thing as a one part waterproof glue.

    Tilt Motor/Pump not lifting

    Make sure the pump motor is getting 12v+. Crack open the cylinder fittings until you get clear fluid and no air or bubbles.

    Rookie of a 1977 Bayliner

    There is a rubber impeller in the outdrive. If you start the engine out of the water and in the boat there is an adapter to attach a hose so the impeller doesn't run dry. The adapter looks like 2 cups attached to a spring and available at most sporting goods or boat store. And big city should...

    Perkins T6.354 counter rotating water pump question

    Raw water pumps either have a flat spot or a reversible anvil that squeezes the impeller. Compare both pumps. Buy new seals and rebuild or send the pump out for rebuild. There's probably a video on Youtube that shows how to rebuild a similar pump. http://www.depcopump.com http://www.waterpumpman.com

    Loose of Power

    Could be air, exhaust, or fuel restriction. My guess is the exhaust elbow is clogged with rust.

    Two Batts for Trolling Motor and Engine

    When the 2 batteries are connected, the 24v will try to discharge thru the 12v. 12v + 24v in series makes 36v. Your trolling motor will run fast for a short time. There are 12v to 24v chargers.

    Date of my Graymarine engine

    As above 1950-53, model 115, see attached. Other numbers on the block are casting numbers and nobody has those. The files model 115 come from one page, but the forum limits a jpg to about 1000kb so I had to split and grayscale one. Gray Marine is long gone, but if you need to overhaul, any...
