Mercruiser Precision Parts keep your engines
in good, safe operating condition.

Insist on ONLY Mercruiser Factory Parts!

We have tune-up kits, points and condensors for every
Mercruiser Sterndrive and Inboard Engine made.

Here are a few simple tune-up tips.
1. Always set your dwell (points) BEFORE setting your timing.
2. Apply dielectric grease to the distributor cam or the points will fail fast.
3. Make a note of you firing order BEFORE the tune-up.
5. Make sure you have the correct engine specifications.
6. Use White Out to mark your harmonic damper timing line.
7. Use care installing a ThunderBolt Sensor wheel! Don't bend any tabs.

Points will wear in two places.
The contacts will get burned and pitted while the wear-block
will also get worn down and out of adjustment.
Start out setting the point gap with a feeler gauge and then
after you have the engine running, recheck the points with a good
dwell meter.
The larger the gap, the lower the dwell reading!
