Common Questions

Frequently asked questions.

How long does a typical engine repair take?
Routine maintenance and minor repairs are usually same-day to 2 days. Major work — top-end rebuilds, lower-unit service, complex diagnostics — typically 3–7 business days depending on parts availability. We give you an accurate estimate before starting.
Do you work on all engine brands?
Yes — outboards, inboards, sterndrives, and diesel from every major manufacturer. We specialize in Suzuki (factory-certified) but service Yamaha, Mercury, Honda, Volvo Penta, MerCruiser, and others routinely.
Can I get a repair estimate before committing?
Always. We diagnose first, write up a detailed estimate, and review it with you. No work happens without your approval.
Do you offer emergency or rush repairs?
For breakdowns during peak season we prioritize based on urgency and shop capacity. Call (419) 357-5891 — if we can fit you in, we will.
What's included in routine engine maintenance?
Oil and filter change, lower unit oil, spark plug inspection/replacement, fuel filter, water pump check, anode replacement, and a full diagnostic scan. Standard intervals: every 100 hours or annually, whichever comes first.
