100-hour service for Stuart's offshore twins and triples
Offshore hours in salt water are the hardest duty an outboard sees, and Stuart's fleet puts them on fast. Boats out of Manatee Pocket run the St. Lucie Inlet in twin and triple configurations, so the hour meter climbs quickly and the 100-hour mark arrives well before the calendar says it should.
On the river side, Sunset Bay and private St. Lucie River docks hold boats that run less but sit in brackish water all year, which means the annual interval matters more than the hours. We service both kinds at the slip: twins and triples are normal work for us and get done in the same trip. Stuart is 20 to 30 minutes from our base and carries no trip fee.

Stuart service cost
A single outboard typically runs the range below. Twins and triples take longer and use double or triple the parts, so multi-engine boats are quoted per boat after we know your engines, hours, and last service date.
- 100-hour service, single outboard: $220 – $380
- Twins and triples: quoted per boat, since they take longer and use double or triple the parts

How often should my offshore twins be serviced?
Every 100 hours or once a year, whichever comes first. If you run the inlet regularly, hours arrive faster than months, so watch the meter.
What is the 300-hour service?
Everything in the 100-hour service, plus water pump impeller replacement, spark plug replacement, thermostat inspection, timing belt inspection, and valve clearance check where the manufacturer calls for it.
Do you service triples?
Yes. Twins and triples are done in the same trip, though they take longer and use more parts, so the quote reflects that.
Will servicing at the dock keep my warranty valid?
Manufacturers require on-schedule maintenance with correct parts and documentation, not a dealership. We work on Yamaha, Mercury, and Suzuki, use spec parts and lubricants, and give you a written record.
