The boat is fresh water cooled. What hotter range plug would you recommend
and how much hotter is it than the standard plug?

Thanks,
Geoff

It seems most new boats have a 160 thermostat these days. I have a '93

fresh water. I want to get the cleaner combustion that the higher temps
give.

Ok, I've a different opinion.

I prefer to run a little cooler thermostat with a hotter plug. I've
done this on my antigue trucks and this technique works great.

If you are looking for power and clean combustion, a hotter plug is
always the best choice over fooling around with the thermostat. You
have to remember that the reason you have a thermostat is to maintain
a constant temperature on the block for expansion/contraction reasons
- not for combustion. Combustion is strictly the pervue of how hot
the spark is.

Curiosity question - raw water cooled or fresh.
