Works For
Boats up to 60 mph with single outboards up to 300 HP or twin outboards up to 450 hp (non-counter rotating) / 600 hp (counter rotating). Twin engine applications require a tie bar kit. High performance boats, top speeds above 60 mph, fast bass boat, or boats with dual-cable steering will require the SeaStar Pro kit. The SeaStar requires a 3″ (76mm) cut-out hole in the dash and a minimum 21″ (534mm) splashwell width.

The HC5345-3 cylinder is suitable for most outboards. Use the application guide in the product images to double-check what cylinder your outboard requires. If you need a cylinder other than the HC5345-3, find the SeaStar kit that comes with it here: HC5347-3, HC5348-3, or HC5358-3. If your outboards needs the HO5090 spacer kit, you can find it here.

This SeaStar kit comes with a 20 foot hose kit, part number HO5120. If you’re unsure what length you need, use the measuring guide in the product images. For different lengths go here.
