Hey everyone,
I'm new to the group and just purchased my first boat this year. It has the 2-stroke 1998 Mercury Sport Jet 175. Did have it running out on the water when I first got it, both when I purchased it and after when I got it home. The last time when we brought it back in there was a bad miss. Looked it over and found a plug wire broke, then others weren't clipped on right. Ended up getting new wires and plugs. Did an oil injection delete too, the plastic gear was on it's way out and I grounded out the oil level sensor. Also replaced the engine temp sensor because it stopped working. Did a bunch of other stuff in the meantime, maintenance and personalization. Getting it ready to put back in the water after sitting for a couple months and now it won't start. It has spark, plugs are wet with fuel and compression on the one cylinder is 113psi when it's cold. Fuel pump does work, however there's low voltage at the enrichment solenoid. I have put 12v to the valve and it works fine. When I first tested the voltage it was around 11, then dropped to 10, and now in the 9 range. Battery is charged up, I've checked the engine grounds, cleaned the terminal going to the ecu, and did resistance test between the ecu plug and the solenoid, checked out good. Not sure what I'm missing here, I did go around with DeoxIT terminal protectant/cleaner on any exposed terminals too. There is a primer bulb someone installed, I gave it a couple squeezes before and it started up. Not sure if it's enough or I should be squeezing it more. I have also drained the fuel tank and added new fuel. Any help is greatly appreciated.
