I have talked with several people running big HP blower motors....and have been told that you can generally expect to get about 150 hours between tear downs......is this fairly realistic....I know it depends a lot on the type of hours these are....but was wondering if this is in fact pretty close to what I could expect if I were to be running big power like this.....thanx for the feedback...Rich 1000-1100 HP range.....

Good question... And + or -, what does a teardown cost ?

I usually get 200 hours if treated right. Need to check the valve train and keep up on the Maintenance. I run Amsoil and it seems to really increase the life of the motors, transmissions and drives. I do change the roller lifters though every end of the season, or spring. Cheap insurance. Rebuilds are very cheap.

It all really depends on how hard you are in the sticks. My brother always says anything over 4500 RPM and the meter starts to run 2 to 5 times faster. If you keep the hours low enough you costs are low, if you wait too long and the engine lets loose then it is big $$$.

I was told by Tommy at Chief you should get 3 re-builds if handled right out of the complete bottom end.

I have never had the boat or engines that long.

I do know of a couple guys that have went 300 + hours on milder Blower motors 800-850 HP.

My .02 only here.

Thanx Scott......I have been told to expect to spend around 20k per motor on a complete teardown, is this about right?? So considering what you have told me...what is your out of pocket expense after this time frame???.....your numbers are in line with what I have been hearing........thanx again....Rich

Isn`t DMAN running 1000 hp Phaff motors and he is getting 400 hrs or so from them?

I know it sounds high, but that figure was posted here before

Well.....that seems to be in line with what I was told initially......that is quite an expense every three hundred hours.....30-40k.......and that is if you keep the R's low and baby the motors......and if nothing catastrophic happens.....I am beginning to think going with a Gladiator with a set up like Pudges would be the way to go.....at least a lot less expensive in the long run anyway.......

We normally freshen our big HP engines at around 250-300Hrs, however we've got a few out there with 400+. The biggest key is maintenance. It is also a good idea to run octane boost in big SC engines, as fuel from the docks is usually not great.
A complete rebuild goes for about 12K, depending on condition of parts.
