Question
Gear Ratio for Mercruiser 140

Hello, My Mercrusier 140 outdrive has a 1.98 gear ratio. Looks like your replacemnt is 1.94. Why the difference? Thanks

Submitted by: Tracy
Answer

The replacement gear ratios will be close but not exact. This is due to the fact that these are aftermarket drives and not factory OEM, so a slight change is mandatory. There is no issue with performance.


Question
Alpha Drive

I have a 1987 Alpha outdrive, SN B720690. My engine is Mercruiser 3.0 L. I want to replace the upper and lower drive units. Which model do I need to get?

Submitted by: Harry
Answer

Question
labor hours

When converting an omc 5.7 outdrive to an se116 replacement how many hrs. of labor are generlly required if done by an authorized marine mechanic?

Submitted by: william
Answer

Hello, it depends. If he has done this before he will be much quicker than if it is his first time. I would estimate 8-10 hours first time.

Question
Mercruiser sterndrive OW878498

I stripped the threads for the hose going into the starboard (right if facing the front of the boat)trim cylinder. I don’t know of any fix except to buy a new trim cylinder. The number in the subject line is the serial number of the outdrive. Is part number 165086 the correct part?

Submitted by: Mark
Answer

We do have a replacement Trim Cylinder available for that drive.
