Looking for a mercruiser service center that wants to work on 575's w/xr. Boat is a 2003 386 sonic. No one local has much experience with this setup. Don't mind driving 250 miles. Please refer -thanks alot.

try Northington Performance Marine

PM Magicfloat. He is in Jasper and can probably steer you in the right direction

i dont think you will find a factory trained merc person yet that knows this motor. most of the one ive seen just read the manuel just as i can, the merc scan tool will be the most help. prob someone in florida should be up on this motor. when i had a prob, the most help i got was calling merc racing myself.. i end up knowing more than my locall shop guys here.paid by the hour for him to learn how the use the scan tool.
good luck

Trail Marine in Orange Beach tunes and maintaines some big H.P. poker run boats, 251-974-5638 they work on alot of blower motors etc.

apache22 someone told me trail marine lost there fountain and formula dealership? rumor?. went down there looking at a 38 and 42 fountain, they would not give me the time of day.was peraproved at my on bank ready to buy ,but before talking price they wanted a credit app. i guess they wanted to prequalify me. was not wearing all my gold chains? bought a newer hustler the next weekend.

hmmmmmmmm maybe, I know they are marking down the remaining Formulas and Fountains, and haven't seen any new inventory, but I figured it was the time of year for that.

anyway about maintaince and tuning, Joe Blair can handle it.

Living loud, let me know if you find anyone reliable. I am from Columbus, Ga not to far and are looking for a good marine mechanic too.
