IMPORTANT NOTICE
Suggested mounts are based on past applications with four point mounting configurations. Since engines, marine gears, engine-mounted accessory weights, horsepower, and installations are variable, it is important to make certain that total package installed weights do not exceed mount capacities.
*Suggested Mounts are based on actual applications—compare the listed mount weight capacities against your actual combined engine, gear, and other engine-mounted accessory weights. Do not exceed listed four (4) point mounting capacities.
