I was out in Galveston bay....put in a new impellar but was suspect of a possible clog in the cooling system. I installed a new temp guage, could not find a new temp sender so I kept the original in. Started engine with muffs...never seemed to go above 140. Water was flowing from outdrive, and water pooring out of prop exhaust port seemed warm to the touch.....not hot.
So I figured maybe the temp guage is accurate, and it seemed the water was flowing. So we took it out. Put it in the water, fired up quick and took of toward the Galveston Causeway. From the boat ramp I was doing about 15 knots.....did this for about 10 minutes non-stop...temp guage stayed at 140...which made me begin to worry because that is unlikely. Like a jackass, I figured I would bump up the speed to see if the temp guage would rise a little (because it should). So I did about 20-25 knots for about 5 minutes with no change in the temp gauge. Found this highly suspicious, so I stopped the boat and cut off the engine. The exhaust manifold was VERY hot to the touch. Let it sit for about 5 minutes and went to restart..turned key, click. turned key, click. turned key, click. Nothing.
No attempt of the engine to turn over...figured I had a bad battery. My uncle dropped his boat in the water, brought me a new battery AND a jumper box. Installed the new battery...went to try and start it...CLICK!! Just one click each time you would turn the key. So I hooked the jumper box to the battery...and again click...just one click with each key turn. So he towed me in. Next day took the starter to get it tested....said it was good. Asked them to test it again, said everything tested out good. They said it could be a selonoid going out...bought a new seloniod and all new wiring from battery to starter, and ignition system to starter....spent all day re-wiring and intalling the starter with new selonoid. Finally finished. Battery read 12.5 Volts, went to start and CLICK!!!! Just one single click. I KNOW the starter is getting 12V and I know the starter gear is extending to catch the flywheel. I can only figure I over heated the engine with that long WOT. This is an old 1966 John Allmand Cabin Cruiser...
How can I tell if the engine is seized? I would usually put a breaker bar on the bottom pully and try to turn but the engine mount is in the way. Are there any other ways to check for a seized engine? Does the normal man have the arm power to stick a flat head in the flywheel and try to turn it??? I am at a loss of mind and money. Anybody know what may be going on here???
