Works ForBoats 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. The SeaStar requires a 3″ (76mm) cut-out hole in the dash and a minimum 21″ (534mm) splashwell width.
Cylinder/RamThe SeaStar kit normally comes with an HC5345-3 cylinder, but this kit includes the HC5348-3 alternate cylinder to fit 1977-1990 Johnson/Evinrude 65-300 HP outboards, 1996 Suzuki 115-140 HP outboards, and 2003-Date Yamaha 25-70 HP 4-stroke outboards. Verify that your outboard needs the HC5348-3 cylinder using the application guide in the product images prior to ordering. If your outboard needs a different cylinder, view the other SeaStar listings. If your outboard requires the HO5090 spacer kit, view it here.
HosesThis SeaStar kit does not include a hose kit. If you need one with a hose kit, please choose one from here. You can use the measuring guide in the product images to see what length your boat requires.
