I ran up on a sandbar a few weeks ago and sucked up a bunch of sand. Motor then temped out and only ran at just above idle until we got home. Temp indication went away and we were able to get underway but not get on plane without the engine either temping out or what appeared to be dropping 2 cylinders out preventing us from getting up to speed. I initially thought I spun the prop, but I checked that with a new prop and when I got back in the water we had the same problem. Boat initially got up to speed and on plane and then temp alarm sounded and after that only just above idle or the engine would hesitate. I removed the lower unit and changed the water impeller and housing assembly. Was scored, blades bent and junked with sand. I replaced everything with Johnson parts and also flushed the engine from the upper discharge port, through the water pipe into the powerhead and removed t stats completely and removed all debris. At the advice of a Johnson maintenance tech I left the entire t stat assembly out and reassembled everything. When testing on muffs I got a weak but consistent stream out of the engine. My questions is, should the stream be more or less strong with the t stats out? I want to make sure I am getting the right indications before taking it out on the water to test for real. Tech said to run without the t stats in for my first outing to flush out any remaining junk and then install them when I got back. Looking for your thoughts. Should the stream be stronger or weaker with the t stats out?
