Come See Us Sometime


We pride ourselves on having one of the cleanest shops in the area.  There is almost always some type of fun project going on at Seven Lakes Marine Service.  The type of service we can provide and level to detail is top notch!

Triton Bass Boat Re-Power


This boat is owned by a local bass fisherman.  His spare time is valuable and wants the latest technology to help him win tournamets.  This year he decided to upgrade his power to the latest clean burning OptiMax technology offered by Mercury.  Changing from a carbureted engine to direct injection, can be almost a 40% savings in fuel.  That adds up fast when you're on the water every weekend!

First Boat To Be Proud Of


This boat had a leak and was in serious need of cleaning and updating.  The motor was tuned up and new decals were added.  The leak was fixed, rigging cleaned up and new instruments were installed.  You can see a smile ear to ear when he goes by in this rig.

1974 Mercury S/R 440 snowmobile restoration


This was a barn find that did not run.  It was truly a ground up restoration.  It involved countless hours on the phone with Mercury marinas all over the country finding new old stock parts.  It is a 1st place winner at vintage snowmobile shows.  His wife bought it for him as a birthday present for $500, if she only knew how much money he put into it!


Powerhead Rebuilding


Whether its a pontoon motor or a 2.5L Mercury Racing 280hp, we can do a complete rebuild from top to bottom.  All factory Mercury parts are used.  Blocks can be sent out to be re-nicasiled, top pin pistons added, fuel injectors cleaned and flow tested..  These motors runs as good as new.  They leave us as they came from the factory. 

Transom Assembly Replacement


Upgraded an older bowrider that had it's steering shaft and gimble ring wiped out.  It is now as tight as the day it came off the showroom floor.  A leaking bellows can cause a boat to sink!
