    Looking at that tower it looks like there is a pivot on the front of the mount would expect it to tilt forward and lay down

    Bought a Used Boat, but what is it?

    If you zip your fly back up and check your ego, you will find folks on this site super helpful. No one is on this site because they go out and buy stuff turnkey …I spent 30 years getting my GTO finally roadworthy doing all the work myself .

    Gen plus is the engine. if the original drive it will have a gen two. Google mercruiser drive identification you will find some parts suppliers who post pics. Gen two has trim cylinders held on with E clips vs nuts on a gen one. Also in front of the prop the gen one is gear housing is...

    Closed cooling worth the money?

    If in salt water yes especially if you get a full system to do manifolds too. If yo are in fresh like me not worth it

    Alarm capacitor 4.3L

    If this relay decides to stop working you will have no alarm. Would probably want to visual to ensure you have 12 v positive to the buzzer. While annoying at least you are verifying the oil pressure switch is functional every time you start the boat .

    If it was in my ski locker would have no issue using it. Having just bought it I would send it back unless you are in a time pinch

    1985 MerCruiser 190

    Don't know how you can test it but yes you can change out the regulator if you can find one. In addition to being trouble prone, I believe they are NLA hence the alternator that most folks do.

    Mercruiser vs. Volvo parts availability

    While the dog clutch is not sexy it is hard to beat a Merc Alpha for parts availability and low cost of ownership. Gen 2 which is current production came out in 91, so plenty of older boats with them installed. Of course this only works for boats up to about 22 ft before they tap out to a more...

    Mercruiser 305 V-8 Temp issues

    then 180 is an issue. Did yo verify the thermo housing is actually 180 -200 with a IR gun? Not an issue only thing would be potential for exhaust leaks

    Mercruiser 305 V-8 Temp issues

    the balls are part of the warm manifold system, allows some cold water to flow to elbows when thermostat is closed (cools exhaust) then should shut when warm water off the thermostat comes up through manifolds. Theoretically cuts down on condensation in cold manifolds by just supplying cold...

    Mercruiser 305 V-8 Temp issues

    depends on what thermostat 140 or 160 140 thermostat should be 150 or so My 160 thermostat runs about 165-170 not being under pressure like in a automotive radiator they run cooler temps so it doesnt boil and lessens mineral scale buildup

    Mercruiser 305 V-8 Temp issues

    Pressure test the cooling system- block of inlet and outlet hoses with pipe fittings, T in a gauge, rig up a way to inject compressed air. Should hold 15 psi relatively indefinitely. If head gasket is blown would expect to see air coming out a cylinder via sparkplug hole and or into crankcase...

    Mercruiser 3.0 LX Mechanical Fuel Pump. I am replacing with a new one is this normal?

    Clamp it in a vice. It will be stiff but should move. Doesnt need vacuum or pressure but there may be plugs in the inlet and outlet that need to be removed . If it doesn’t move return the pump.

    Mercruiser 5.7 with V6-14 TB IV module??

    Attached is a helm wiring digram. It show the purple coming off the key switch thru the kill switch, then daisy chaining through the gauges to supply the alarm and then the purple ignition wire. you are likely losing the 12 v on the purple though the multiple connections. The alarm isnt to put...

    Mercruiser 5.7 with V6-14 TB IV module??

    What is the blower alarm? All the kill switch should do is interrupt 12 v ignition circuit from key to engine harness. I’ll see if I can dig up a helm digram

    Mercruiser 305 V-8 Temp issues

    If the hose is getting stiff and the elbows and risers are hot then I would think water flow out through the exhaust is impeded and manifolds an risers will help. Did you verify that the ps cooler is not blocked? Some where there is a flow test for alpha one drives. I think like 3 -qts in 15...
