HP500 carb
 

How is this engine?
Reliability, power, responsiveness?

Who has them for power and what are your opinions?
What is the stock exhaust?

How does it compare to the 525?

Re: HP500 carb
 

i got twin 500hp carbs in my 30 spectre and they run flawless, tons of power, idles well, pretty responsive (my boat is pretty light and moves well)... i have gils for manifolds, probably will swap to some cmi's because i already have them.... i saw they are down probably 50-60 horse to a 525 ( i am guessing efi is what you are meaning, if you mean 525sc i don't have to much exp. with those)... great motors, just watch the valve springs....

Re: HP500 carb
 

Yes, compared to the new 525efi.
I, for some reason, prefer carbs.
And yes, I've heard about the valve springs. What's the proper fix for that?

And can someone post pics of them.

Re: HP500 carb
 

just put some better valve springs in, i got some cranes in mine now, i probably will still swap mine every season, just cheap insurance and mine is at high rpm alot.. :D

If you do a search in the tech section you will have all the info your looking for and then some :cool:

Re: HP500 carb
 

I am a little curious that you are not considering the 500efi You said you like carb but I have had much better experience with the efi models. Anyway I currently have the 500efi with 350 hours, I also replace my valve springs, you really need to with these motors, I had a broken inner spring at 275hours, got lucky and no problems but I will be replacing them every other year now. :D As for power it does every thing I expected it to, no disappointments.

WILL :evilb:

500efi's are coming hard too find... 525's are much easier

I've got 2 500EFI's for sale for $32K 65 hours absolutely mint condition. Original hours, not rebuilt.

Re: HP500 carb
 

Aside from the valve train issues, I would have to
say their as reliable as their "black" siblings.

I have no complaints with mine, they do everthing
I ask of them.

Standard exhaust was MerCruiser Gil's.
( just like the ones in Scott's pix's)

Re: HP500 carb
 

Semper Fi, do you want two 496HOs in trade?

Re: HP500 carb
 

NO, sorry ---- I need to sell the EFI's. I am having the HP500 carb motors rebuilt right now and I need to sell the EFI's for a downpayment on a house. Our dreamhouse just became available. It has a RV garage attatched so we can keep the boat at our home. I can also keep my truck and Marylou's car in the garage as well. :D

I keep my boat in storage and it costs me $240 a month. I have to call 24hrs in advance to get it. I only have access 3 days a week :mad:

here's a link to see the floorplan.
