Hello, I have a 70hp Suzuki four stroke. The boat got stuck under a dock and was partially submerged when the engine was tilted up. Only the front/bottom of the engine got wet. I immediately rinsed it in fresh water and have started to try and get it running. It starts after a few tries if I give it throttle and will run on 3 cylinders only. The bottom 4th cylinder is not working. Where do I start? I'm guessing clean or replace spark plug and maybe spray WD40 inside? Could this be an electrical issue? Thanks for any advice you may have.

If possible, pull the boat and motor out of the water, remove cowl and rinse with fresh water thoroughly, let it air dry and/or use an air hose, then start going through all your electrical connections to inspect, clean, lubricate, re-tighten. Remove, inspect and replace all spark plugs, as required. Check, clean fuel filters, pumps, fuel lines. If this was a salt water dunking then take your time and do it right and you should be O.K., hopefully!:eek:

my manual gives a procedure if engine is submerged. find yours and follow it. If not, previous thread is what most recommend, you may have water in one of the carbs.
