Repower

Repowering with the F350
at Coastal Marine.

Coastal Marine is an Elite Yamaha dealer and an authorized Yamaha Repower Center on Shore Drive in Virginia Beach. A repower with the F350 takes the old or worn-out outboard off a sound hull, of any make, and puts the new Yamaha on, with the controls, gauges and rigging the new setup needs. Warranty work on the Yamaha power we install is authorized in-house.

We don't post engine prices. Tell us the boat, what's on the transom now and roughly how many hours it has, and we'll quote the F350 for it. Financing is available on repowers through Yamaha Financial Services.
