Powerhead Break In Instructions

Hrs. 1-2: Trolling speed-under 2,000 rpm. Vary speed.

Hrs. 3-4: Under 4,000 rpm. Vary the speed (bring on a plane for a few minutes and off a plane.)

Hrs. 5-6: 4,500 rpm. Vary the speed.

Hrs. 7-8: Under 5,000 rpm. Vary the speed.

After 20 Hours, Change oil and filter. Inspect motor for any water, fuel or oil leaks. Report any leaks ASAP.

Thereafter: Use at any speed but avoid continuous wide-open speeds until 20 hrs.

Important: Please note that we bore and hone engine blocks ourselves, and hand fit for exacting tolerances. Our rebuilt powerheads are not built ‘loose’, like mass produced factory units. Therefore, it is very important to follow our break in schedule. Disregarding the break in instructions will likely result in piston seizure, resulting in mild to major damage! Engine damage or failure caused by running the motor too fast too soon will not be covered by warranty, and this type of damage is easily detectable by compression testing or visual inspection.
