[QUOTE="Pappy, post: 284792, member: 3278"] If it was coming out on both sides fairly equal you are probably good to go as far as blockages go. The thermostats cannot block flow to the overboard indicator. That indicator line is just a verification that the pump is working. There are muffs on the market that will not grip the gearcase tight enough to feed the water pump. You may have a set. they are plastic instead of the heavy metal rod shaped into a Vee. Some will some wont. Another way to check your muffs is to remove the plastic screens covering the water pick ups on the gearcase..... if you have the ones with two screws. Run it on muffs without those and see if the pump will develop sufficient pressure and volume. Indicator line should flow if your hose will feed enough. The unburned fuel/oil in the exhaust is normal while running on a hose. Disregard it. Put everything back together and take to the ramp and run it if the above doesnt work. Place your hands on each cylinder head after a couple minutes. Read the above posts on what to feel around 135F. I Will be gone through the weekend and early next week .................. [/QUOTE]
