  1. Re: Male Spade Connector on Boat Rocker Switchboard broke off, is there a fix?

    It might be possible to take the switch apart and soldier wire or an extension. Sometimes there's an fuse/breaker for each switch and you can attach there (if you know what you're doing). Or you can...
  2. Re: Would like to add a temperature alarm system to my 4107

    If you have wet exhaust, there are temp sensors that mount on the hose. Usually when I start an engine I feel the raw water hose/pipe where it exits the engine, before it enters the exhaust. You will...
  3. Re: Volvo D41 smoke from breather and air filter. Help

    A compression check is a good way to eliminate valves and rings from the problem. It could be a spun bearing in the turbo. It's common in older engines or engines with poor maintenance to have the...

    Re: Volvo penta power issues

    I'd do a compression test. One or two cylinders might not be giving their share of power from a ring or valve problem. Could there be some intake air restriction the other engine doesn't have? I...

    Re: 6-71 engines bubbling

    Cavitation is a problem in high hp diesel engines. Wet or dry. It is the forming of bubbles on the surface of the water jacket. When the bubbles pop it causes pits in the water jacket. More...

    Re: High oil in 4.107

    British machining about the time of your engine required a lot of hand fitting and filing. Not like today where you can buy a part, replace it and go. You'll see if you read about replacing the...

    Re: High oil in 4.107

    Most likely the seal on the front of the pump.
    The 4108 is used in farm equipment, probably the 4107, too. So a farm equipment dealer is one place to look. Best bet on timing is talk to a shop the...

    Re: Perkins 4107 coolant system problems

    Reassembling your engine? That changes things. If you had the head off, some head gaskets don't have all the holes for water passage between the head and block. They can create spaces for air to...

    Re: Perkins 4107 coolant system problems

    Ran at idle? The could be air pockets in the hoses, etc. Sometimes the thermostat will keep some of the air from purging. If you were at idle, the thermostat may have never opened because the air...

    Re: Tamd41a (or b)

    Too much soot is too little air with the fuel. Anything that restricts air flow in or out of the engine is where to look. Besides what you've done, is there enough air coming into the engine space?...

    Re: AQAD40B overheating

    I had a yard and fixed a number of heating problems not solved by other yards. The most common fix was cleaning the coolant side with a good descaler that removed rust. A lot of owners run water only...

    Re: Low rpm at full throttle

    I don't think you'll make a big difference. For higher rpm either a smaller prop, less pitch, or some combination. To go faster, bigger motor or lighter boat.

    Re: 4-112 won't run for more than an hour

    Coil could be getting too hot. IF you're running a 6v coil on 12v, that a failure waiting to happen. If the coil gets too hot, the top pops off and oil comes out. I did that once 4 wheeling with A...

    Bad connection, probably somewhere in the ground. Look for corroded connections, wire brush them, etc.

    Re: Heat Exchanger Repair

    I could fix the exchanger, I doubt you can.
    If you're loosing coolant and it's not in the oil or bilge it's usually the exchanger. It's possible to loose it thru a head gasket. You can pressure test...

    Re: 6v53 natural

    At 185 the thermostat is wide open. Any more heat and more strain is put on seals and gaskets. While most diesels run more efficiently at hotter temps, about 210 or so, Detroit doesn't like it. And...

    Re: 6v92Turbo not building oil pressure

    I meant the bypass valve in the bottom of the spin on oil filter. The bypass is there for people that don't change their oil and filter. If the filter plugs the bypass opens so the engine gets oil...

    If you can't find a source for the coolant, try putting some toilet paper around the hose connections, cooler, etc. or use something like powder anywhere coolant flows. Sometimes even a quality hose...

    Re: 6v92Turbo not building oil pressure

    A collapsed oil filter. The filter bypass should open, but is it's a cheap filter... Is it a high hour engine? Could be bearing wear and/or pump wear, but it doesn't suddenly happen.
