Re: 1756 evinrude no water from exhaust ports after run aground
After the initial post i removed both thermostats, put the covers back on and tried to run it again to be sure the thermostats were working properly and still no water out the exhasut ports? The thought of removing that lower unit again to flush gives me nightmares. The lower unit is no big deal, pull six bolts, take off the trim tab on the bottom of the cavitation plate to get to the last bolt, the real issue is the shift linkage on this vintage 1985. You have to release and remove a bolt located under the carbs that takes a lot of dexterity and patience, along with a 12 inch 1/4 drive extension and a 3/8 inch swivel socket on the end. You also need a magnetic pick up tool on a telescoping antenna type thing, (I recommend everyone own one of these) to hold the bolt in place, while shimmed from the magnet with a piece of matchbook on one side to slightly angle the bolt on the tool in order to get it back in the hole in the shift shaft plate under the carbs. I searched high and low for advice, the manuals kind of avoid the topic, and there are a couple of different set ups. Some said remove the cowling, remove the carbs, etc, seemed like a lot of work to change an impeller. Think it might be easier to remove the exhaust plate between the heads and look at it from that aspect, any thoughts?
