i have a salt watered cooled universal 5411 model, i noticed that there was litle water being ejected thru the exhaust, i have already taken off every hose ,cleaned them out , checked the impellor for proper operation, and it appears there is a blockade between the impellor input hose into the engine block and the output hose at the top of the block.i did notice that the water pressure being ejected from the impellor was equal to a garden hose being turned on to approx 1/3 pressure, does anyone have any advice on what i should do next, check the thru hull for blockade -?, use drano for cleaning the system.would appreciate any advice. j

Little water is NORMAL! :)

I get flagged down by other "helpful" boaters all the time because "I'm not pumting any water!" Every once in a while a spit of two of water pops out. It's completely normal. The Universal 5411 is a fresh water cooled engine and it very seldomly opens the thermostat all the way because the engine never really gets hot enought. Other "helpful" people point out that I've "got problems because it's blowing white smoke." It's not white smoke, it's steam and it's normal to see it from the exhaust of the 5411. If it's whispy and disapears quickly after exiting the exhaust, it's steam and is normal... I agree that the 5411 is a great little engine, as long as you don't have to power into a gale or 5 foot chop.
