Purchased duck boat about a month or two ago, came with two outboards.
the 15hp force/chrysler
i replaced water impeller and gasket and make sure I blew through lines. Also replaced lower gear oil. Took forever to realized top exhaust port doesn’t really spit water unless boats actually on water as opposed of garbage can test. Finally tested boat this weekend
boats 150lbs fiberglass
i got out there she started up good, started going went to max throttle a whole 15mph I was shocked thought the motor should do a lot more than that, spoke too soon motor changed to top speed of 7mph.
went to test reverse when I idle slow it shut off. Took a while to start had to move throttle quite a bit past start to get her to turn over. i drove full throttle 7mph back to boat ramp
now during full throttle felt like it would speed up a little slow down. Kinda like wah wahhh wah wahhh wah wahh sound.
i do hvac don’t really work on outboards
now I know I have a 2 blade prop which is not OEM calls for a 3 blade.
next plan is to rebuild carb
replace prop with OEM maybe have prop spun on old prop
replace inline fuel filter
replace both spark plugs.
and to reiterate about water impeller I can run it with my hand in engine in idle and engine block stays about 70 degrees
motor does not have a thermostat either.
also removed bottom spark plug to check if water was leaking to into engine area did not see any but bottom spark plug was clean.
all helps appreciated also when it get new parts any tests I should do? Anyway to tell if I have a bad coil? I own an electrical meter and stuff.
