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 - make sure to 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.
