great diagnostic tool....

[Lou C]

Just picked up a Radio Shack laser thermometer, these things make it very easy to check important things like manifold/exhaust tube temps, verify proper thermostat operation, etc. I found that my new manifolds run at 115-118* idling through the channel, and 135* or so after running on plane for a while. The hottest part of the engine was the part of the intake manifold where the thermo housing is bolted to it, this came in at 155*. This boat has a 160* stat, and runs from 160-170 usually....

Have used mine for years to check hub temperatures at every stop on trips. Great way to check for bad wheel bearings or brakes hanging up on my trailers.
