Took my boat to outboard motor service and mark said the diaphrams inside the vro were shot so heres what they did: checked compression it was good, re-gapped the plugs, removed shrouds, replaced vapor pump diaphram, glued in air disc, replaced res, needle, and seat and set height, replaced vro pump, bled out hoses, did no oil metering and alarm test and while he had it apart i had him replace the water pump impeller and he topped off my lower unit lube all for the low low price of $1101.62. Im sure i could have got it done cheaper somewhere else but when i first went there and talked to him he showed me around the shop and showed me some vro's he had worked on and i was impressed with his knowledge of my motor. Besides how much is piece of mind worth when your out on the lake with family and friends and your confident your motor will fire up everytime , in any situation, because you had professional job done. Id recommend those guys to anyone as long as they're thick skinned cause his personality can be a little off-ish. Kinda high strung. If you ever met the guy you know what i mean lol. Im happy with the job, the motor runs great now,no alarms, and im a satusfied customer. Happy boating and tight lines
