I fully agree with George this fella picked up thing on the set up of my rig that where wrong and my boat is new
I have met over 30 blokes who use him Not one went away feeling ripped or unhappy with his work
He will do the service in front of you if you want and explain what he's doing
Some of the things he does as standard are compression test ;oil change; battery cell test'; spray protective spray on battery terminals ;carbon decarb if required , Grease up nipples check and grease trailer wheels Grease accelerator linkages, check battery for charging from engine , and he also did a water test for me as he found my outboard sat too deep and the prop was to big My boat gained a extra 1200rpm and 14km by him setting it up
