Ok, so factory starter bit the dust, shopping for a replacement, considered Denso, but finding o real one concerns me, and the fact that that they only use 2 bolts instead of the 3.
Considering Power Master.... good? bad? Ugly?

Thanks
Mike

 

@ESwift is able to help you purchase a genuine Denso.

The two bolt configuration has not been an issue for me, but I used 15mm longer boots due to the mounting surface. I also used the OEM lock washers and since installing it 5 years ago, I put a wrench on the bolts at each oil change just to check.

Calling @RacinJasonWV and @Wes444 to the customer support desk for references on the Power Master starter.

I have zero complaints about the Denso, but also recommended the Power Master to a friend just last week.

Thank you Sir!

I prefer the Denso. Have run one for years, and will continue to put them on all my trucks.
The guys at cncfab can get you hooked up, thats where I got mine

 

According to my pic dates I've had my PowerMaster since December 3rd of 2021.
Yes it has 3 bolts vs 2, but that 3rd bolt makes you earn it

 

The Powermaster has good reviews. I’ve also seen good comments about it on FB.

That’s the brand I’ve had on the race car for many years and haven’t had any issues.

The Powermaster is quite a bit cheaper than a real Denso.

I purchased one for the truck based on this info. It’s been installed, but haven’t touched it any more than cranking it over a few times in the garage after install. Salty roads, truck stays tucked away.

Here’s a link to my install info. I tried to take a comparison video before/after but found a loose terminal after the swap. Also, it seems some dummy had the door closed in one crank and open during the other. So the sound isn’t a good comparison either. I’m a failure.

Either one should work well. If going with the Denso I’d order from CNC Fab so you know it’s real. Otherwise I purchased the Powermaster from Summit.

 

I'll add my 2 cents...

I have the powermaster sitting on the shelf, I got a good deal on it and grabbed it for a spare. I have not used it yet but powermaster has been making reliable components for Fords/ vehicles for a very long time. I wouldn't hesitate to buy one.

I have run the chinese DB electric denso which lasted a few years. I still have it somewhere and upgraded some parts on it with genuine denso parts. So technically it still works just fine.
Then I switched to a Genuine made in Japan Denso from Larry B's many years ago. It started acting up last year. I think I need to open it up and either clean the contacts or replace them along with the plunger.
I had a newer genuine Denso that I purchased from National Starter in 2018 sitting on the shelf. They are made in Thailand now IIRC... This is what I am currently running.

I have been running a denso for at least 10 yrs now and I am using the factory bolts with no issues. The great thing about the Denso is how easy/ cheap they are to service/ fix

there are more recent starter option threads and it seems many are using newer ford starters from 6.0's, 6.4, maybe 6.7's with great success. I think you just have to swap over a cover or something, can't recall. They are high torque but smaller. Just another option to look into

no matter what route you choose, you'll be amazed how much better these starters are than a factory 7.3 starter. it's like having a supercharged starter

 

Another happy PowerMaster starter user. Link to my install below:

OP,

For the 1999-2003 Powerstroke, our customers typically choose between the Motorcraft SA817RM and the Powermaster Ultra Duty 9051, each offering benefits depending on your needs.

Motorcraft SA817RM

• Rating: 5.0/5 (3 reviews – Summit Racing)
• Overview: A direct OEM replacement, built to Ford specs for reliable performance.
• Core Charge: $20.00 per item. Refundable with a suitable old core (customer covers return shipping).
• Feedback: Highly rated for reliability and ease of installation. Ideal for those wanting plug-and-play stock performance.

Powermaster Ultra Duty 9051

• Rating: 4.75/5 (121 reviews – Summit Racing)
• Overview: High-performance upgrade with 3.80:1 gear reduction, 260 ft-lbs torque, and 3.6 HP, offering stronger cranking power for cold starts and heavy-duty use.
• Installation Note: Includes a third mounting bolt for added stability, but some users find it challenging to install due to limited space.
• Feedback: Well-liked for stronger, more reliable starts, though slightly louder than stock.

Which One to Choose?

• Motorcraft SA817RM – Best for OEM reliability and a hassle-free replacement.
• Powermaster 9051 – Best for extra cranking power in cold weather or heavy-duty applications.

Both are solid choices to keep your 7.3 Powerstroke starting strong! 💪

 

Thanks for the input, Power Master inbound.

 

I don't have a power-master on my 7.3, but I do have one on a high compression Big Block Cadillac engine, it spins it like a top, has for almost 10 years.
The ger reduction is noisier than a stock style, but for cranking power they are hard to beat.
My old starter would barely turn out the oil light while cranking, the power-master will give my 25psi of oil pressure on the gauge.

 

Plan ahead for the top bolt. I don’t think it would have given me much of an issue with the right tools. My guess is best way to access is by using some type of flexible handle wrench that will let you turn it from the rear (trans) side. My normal wrench would run out of room to turn before being able to grab a new bite.

Also plan ahead for a rubber boot on the large cable.

Get those 2 things lined out and you should be golden. Can’t wait to hear your review.

Edit: ​​​​​​@BWST you have any tips for getting a tool on that top bolt?

 

Racing,

Thanks for the heads up, did you get the top bolt in, or just did without?
Reading about this on the net, one guy used a 1/4 inch ratchet adapted to a 3/8 socket/ extension.

 

My experience is described in the link I shared earlier.

I did get the bolt in, getting it tight was challenging because of the shape of the starter webbing. I wasted a lot of time going on/off the creeper looking for a good tool.

A 1/4” socket with universal and extension probably would have worked, but my 1/4 socket set didn’t go up that far. The Powermaster comes with new longer bolts that have a 17mm 15mm head. I checked multiple tool sets looking for that 1/4” socket. ☹️

Here’s some photos. Most of these are in the other thread too.

Heads up, there’s a spacer used on this starter. You also have to straighten out the 90° terminal. A rubber boot would be nice. I used split rubber hose for now.

Thank you Sir.
