9 tooth versus 11 tooth starter-gctid816024

[itsabowtime2]

I looked around all day for a 9 tooth, gear reduction SBC starter. That is what I removed from one of my engines.

After spending about 45 minutes on line I found 1, one listing stating the 11 tooth starter replaces the 9 tooth.

Is this valid? It is Go 2 Marine starting this.

i belive DB's site states the same thing. Has to do with how the manufacturer builds the starter, different type of nose cone etc.

Pay no attention to the pinion gear tooth count!

The important aspect will be the "straight across" bolt pattern versus the "staggered" bolt pattern , and this will be specific to the amount of teeth on the flywheel ring gear .

Just so you all know that's kind of a inside joke between Rick and I.

Bendix drives are not that great. I think if I had a crank handle on the front of the engine I could turn it faster.

I guess I'm just kind of a purest I choose to leave my bendix drives the way they are but not the best design. Just don't let your battery get too low or it won't crank fast enough to start.

Your 1998 boat is likely GM V-8 powered, and is likely Mercruiser w/ a Std LH Rotation Engine........... correct?

If so, you will want a HTGR/PMGR starter motor with the "staggered" bolt pattern nose housing (i.e., for the 168 tooth flywheel ring gear), and in the CW rotation for the Standard LH Rotation engine.

Be sure to get the correct length mounting bolts for the new starter motor. [/color]

Will find out today.

I have power at the ignition, power at the starter, power at the solenoid and the starter bench tested poorly.

The only starter that matches up in diagrams is a Sierra 18-6275. Merc. 50863007A-1

It is defiantly a gear reduction starter, staggered bolt pattern starter with 9 teeth. If it is original equipment I don't know as I am the second owner and have had the boat for 4 years. This is the starboard engine (looking bow to stern).

What is interesting is if you look up the specifications for the Merc part number there is no mention of CR: https://www.wholesalemarine.com/merc...863007a-1.html

Go 2 was the first site I found that specifically stated to use the 11 tooth in place of the 9 tooth.

I never would have thought that replacing a starter on a SBC from the late 90's would be so challenging. On some listings it states the 18-6275 is the recommended replacement for the 3.0 but is also for all SBC with 14" flywheel.

Best I can tell recall my engines are standard rotation..

Based upon WM and Wholesale Marine look up based upon my engine serial numbers this is the starter:



Here is a photo of what I removed:

The mounting alone is incorrect along with the cone.

Had a very similar experience looking up my then 94 5.0l starter.

Turned out the starter was good.

This starter is the one I bought, yours will be the same, works great but no steel gears.

[itsabowtime2]

Based upon looking up that part by year, engine size it is this:

The difference between mine and this is the cone opening is smaller on this one. Overall cone size is the same, the opening for the gear is smaller. Beyond frustrating.

I may end up just getting the one I pulled off rebuilt.

You didn't see the link :huh: This one.

Good starter for lots less than most places.
