- Dual Mercruiser 5.0 Bravo III Stern Drives EFI
So I have a 1988 Sea Ray Amberjack 270 fitted with two i/o mercruiser 5.0 bravo III stern drives with fuel injection system. Engines have about 700 hours on them. Ran a compression test at end of season last year and everything was in good order. Spark plugs looked good. Marina winterized it, used fuel stabilizer, all the stuff your supposed to do. The marina changed the filters and fuel/water separators this year. Took the family up this past weekend, started great, ran great for about 30 minutes then poof starboard engine is gone once we got down off plane. Thinking it could be a fuel issue I switched the fuel for the starboard to the port side tank and it started right up... lasted a whole 2 minutes then stalled out again. So now I've ruled out the possibility of having one bad tank cause it won't work on either tank even though the port engine runs just fine. Limped back to the dock with one engine (thank god we had 2.. redundancy for the win). Still couldn't get it started again.. turns and turns but won't start. Kind of worried I might've done some damage trying to start it cause we got a nice little puff of blowby after a few more tries. Packed it up, went to the bar and drank about it for a while. Now I'm here! I've seen a few people mention IAC valve could be bad. Is that a good place to start? Would like a few things to try since the boat is about an hour away from me and I'd rather have everything I need for the day of repairs. Thanks in advance!
