changed my gassy oil 2 weeks ago,oil was up on dipstick and stank.03 YamaF90.not alot of hours on the oil.20 maybe in 5 months.last time ran was on the muffs at idle after oil change to check level and leaks.changed plugs today and #1,3,4 were about wet and stank.I could smell gas strong when I removed the cowl.no aparrent leaks under cowl.could my carbs be leaking down into the motor while it sits? I do not have a quick disconect as there wasnt one when I bought the boat in 07.do i need one? 12 gal.plastic tank w vent on cap left open a turn.do I need to drain the carbs somehow if it sits 3 weeks.or do my carbs need attention?in a recent post an identicle boat w new fuel injected F90 said he got 5700rpm @ wot w a 19 pitch 3 blade prop.I had a 17pitch 3 blade until one engine hour ago.now a 17 solas 4 blade alum.so I assume my wot rpms are close to right now,range is 5000/6000.
