Need to replace my starter making a weird grinding screeching sound when I turn the key so I'm just going to replace it. My question is how do I know if my flywheel is 168 tooth or what tooth it is period? ?
-
oh and it's a bbf
-
Maybe pull the part number off of the old starter and use that as a reference
-
I took mine off walked in to my local auto parts and asked them to match it!! Hard to find parts of years and type motors on my boat
-
I believe the most important part is to make sure it spins the correct way
-
thanks guys I appreciate all the info I get from everybody on this site really helps out

I switched to the gear reduction starter off a newer ford pickup

:thumbup: :thumbup:
After years of using Kragen starters with replacement warranties and going through 1-2 per year, I bought a More Power gear reduced starter about 11 years ago and am still using it. So much easier to work with and handle due to the reduced size and weight, and it cranks!

The direction it spins is crucial. If it mounts down below the headers I think it needs to spin reverse of a stock truck starter. Confirm this but I definitely recall this issue in the past.
One time when I was a youngster we replaced the starter on our bbf, got everything back together and started cranking, and cranking until we realized it was spinning the motor the wrong way. I guess the spray of fuel coming out of the carb should have been a good indicator...

I went down to oriellys bought a brand new starter, pulled it apart and used the parts I needed to refurbish my old one cuz my original is thick and not a cheap repop runs killer pretty easy to do

This is Absolutely, fundamentally, WRONG....Its just a jet boat...All jet boats are STANDARD rotation, PERIOD.
As far as the O.P.'s Question, Using the year of the boat, 1977? 1995?... Just get a starter for a 19xx F250, 460 auto, etc.
There is Summit, Jegs, any number of marine superstores/mail order places...
Swap out the USCG screen if it has one, to the new starter...BAM boats ready...

Are you sure that is correct?
-
Are you sure that is correct?
For a BBF using a stock style starter on the block? YES
For a turbine boat with a $20K reverse rotation custom pump? Well, no. I don't believe this is the case.

Call IMI Performance Products and buy a hi torque mini starter. I've had one on my BBF for a few years with zero issues.

Not necessarily true, but more true than the post you were referring to.
Where you f'ed up was "all jet boats".
There are quite a few reverse rotation systems out there. Just not what we normally come across.

If the starter mounts in the bell, behind the flywheel, it's considered reverse rotation, if it mounts in front of the flywheel, it's considered standard.
You can pull the starter off your F250, bolt it in and go.
I think a little something was lost in translation.

Wow take it easy tiger. You are wrong my friend because there are 2 styles of starters for most all jet boats. Like GT said there are regular mount styles and there are the reverse mount that go on the bell housing.
I had purchased a replacement starter from a boat shop that was intended for the bell housing mount. When it was installed in the stock location it was turning the motor backwards. Even experienced rebuild shops can take a regular starter and wire it to spin the opposite direction.

Now you are blowing it out of your butt. :-*
The starter armature and Bendix are completely different between the two. The only thing a genny shop can do is reverse the stator. The rotor and Bendix will need to be swapped or for the proper rotation unit.

Ok Einstein. You win; you also lost me but you are the winner. The point I was making is the rotation of the starter is important. I speak the language of a layman who does this for a hobby, not a living.

OK,
Layman's terms, how would the bendix throw on the threaded output shaft is it was rotating in reverse?
Answer; it simply won't.
The way the Bendix moves is the rotation of the shaft "screws" it forward. Also, the Bendix is a one way bearing assembly that would "free wheel" if rotating backward. So it would never drive even if the action of the Bendix is mechanical like a GM starter.
Not trying to be a wise guy. Just keeping the information as real and accurate as possible.
If I'm wrong, feel free to right me.
No offense intended nor felt.

Lol. Good video.
Thank you for the explanation. Makes sense. I was under the impression a starter could be made to rotate in reverse but probably applied the wrong terminology for the execution.
No offense intended or taken either. You are the tech master-I mean that sincerely.
