Hi guys,
I can't find a service manual for re-filling my ARCO Tilt pump (picture attached)
There's an obvious screw/nipple on the front facing downwards, would somebody be able to confirm that I can fill the reservoir with a syringe using that nipple? Would really appreciate some advise in this...
Hi guys,
My Mercruiser 470 3.7L has a Circulation Pump leak on the second seal so all coolant is dumped into the oil pan. I've currently taken off the oil Pan to clean out the coolant/oil mix and am slightly worried about the lack of coolant in my engine during the winter months. Will the...
Okay that's sound advise. I know exactly what you mean about getting a longer centre bolt to reinstall the balancer. Thanks alot for the great help. I'll crack on tomorrow morning. 👍
Hi mercruiser boaters,
I'm trying desperately to remove the harmonic balancer from my 470, as I need to change the Circulation Pump gasket behind it.
Does anybody know what thread/size bolts to use for a puller? Most likely they are imperial and the cheap puller I bought from an auto shop only...
Hi Guys,
Not sure if any of you have experienced this but my starter motor (original to 1986) is seized/rusted into the recess of my flywheel housing. I've removed the two bolts, tried knocking it with a hammer and pulling it with a torque strap clamp. It seems that it Rusted all around the...

Bit of an odd scenario, but a mate of mine who is an engineer but not familiar with Mercruiser's serviced my sterns, and when testing the portside engine, he put a pressure hose in the water inlet with sterns off without cranking the engine. Flooded the engine with water and then cranked it with...
Hi Eric,
That's the exact manual page I was searching for thank you.
I guess I need to persevere. The reason I need to get to the circulation pump is that I have coolant pouring into my oil pan which I've ascertained it could be the timing chain cover seal (gasket). So I'm going to replace the...
Hi guys, this is my first post here so please be gentle.
I have a Mercruiser 190hp 3.7 (470?)
I'm trying to remove the Harmonic Balancer to get to the Circulation Pump case behind, I've tried using a puller with the three bolts in place and socket torque wrench won't budge. Are there any hidden...
