Just bought a lazer guided temp. gun from Maplins £50 for work use. How useful could this be on the boat especially if there are two engines to compare. How often on a long trip do you look under the hatch to check the engines when they are working hard? With a flash of the lazer you can check the difference in temp between exhaust risers,injectors,sparkplugs,hoses,cylinder heads or water pumps etc. I also recon it will work on running drive belts . You can also use it at home to check your radiators etc.
