Outboard boat engines no pee hole

Del Mar, Ca Hey all; I have made enough progress to actually try starting up the outboard today. Replaced some electrical cables, replaced the brakes on the trailer and got the wheel back on, charged up the batteries, drained most of the fuel out of the tank and put 5 gallons of fresh premix in. I also fogged the cylinders as someone here recommended, and cranked the engine over a few times by hand to lubricate the cylinder walls. After all that, I hooked up the fuel hose, connected one of the batteries, and set it up to run on muffs and garden hose.

Tip for fouled outboard pee-hole - no repair required quayman posted But no new water impeller nor water pump was required for repair. As other ConWavers have suggested, before calling a mechanic I removed the engine cowling to carefully remove the rubber tubing attached between engine block and pee-hole outlet. Then, I used guitar string and a straight piece of coathanger pushing Q-tips to clear out gunk that had clogged the rubber tubing. The pee-hole gushed when I fired up the engine in a water-filled garbage can after re-attaching the tubing. If you trailer your boat, and you trim up the engine when loading your boat back onto the trailer from the water, make sure you take a moment before going home to let the engine down so water can drain out before trimming back up and applying the transom saver. That way, any debris sucked into the engine water intake - such as silt - won't sit inside your engine, potentially fouling your systems.

Sometimes it takes a little bit to get a stream going, you want to be very sure you have the muffs positioned correctly, may have to move it a little while running. I've never seen someone tilt the motor, usually because you are running on muffs to do oil change or something so tilting would be bad. I see some say the technical name is overboard indicator, pretty sure not many would have a clue what you're talking about if you said that! Haha, I just call it the pee stream!

So, to the problem I imagine this is salt build up, or possibly something once living crawled up in there Do you think I am probably right in thinking some sort of buildup? Anyone any clever ideas on how to rectify this, without dismantling the whole thing? Any solutions I could use that could be pumped in to dissolve the buildup?
