Hey guys this is my first time posting, hopefully this is a very
active group. I recently purchased a 1980 Silverton Convertible. I
have conducted daily boat checks and engine checks althought i find
that my port engine over heats. Not over heating to the point of
seizing but around 230 degrees. Some people tell me that i may have a
tachometer issue althought id rather be safe than sorry.My starboard
engine runs beautifully without any issues. If anyone has some ideas
or ways to inspect the engine for possible problems, please post up.
Thanks alot!

John, first see if the gauge and sensor are working properly. It's
easy just to swap sensors and wires on the gauges. Next, change the
thermostat, it's easy and cheap, so why not. Check the raw water inlet
hose, is the inside clogged? Is the heat exchanger for the engine and
transmission clogged? Next, feel the exhaust manifolds and risors,
they shouldn't get hot. Check your raw water pump impeller. Is the
engine raw water cooled? If it is the blades on the circulation pump
may have rotted off if it's not a marine unit, the block can also fill
up with silt over time.

Thanks alot appreciate it

I just went through thsi with my port engine. My block was full of
scale and my heat exchanger had silicone all over it. I did two
things and not sure which one fixed it.

1. I had the heat exchanger ultra-sonic cleaned. Like a big jewerly
cleaner.
supposed to be the only way to clean silicone from exchanger.

2. I used some products from Penray to clean the scale from the
block.

www.penray.com I used the twin pack for cleaning and conditioning.

I was running at 200 to 210 and now Im running 180.

Good luck,

Dan
