Was looking at the Hardin Marine Stage 2 Upgrade for Mercury 525 EFI. Just wondering if it's worth the $2k or save a little bit more $$ and put a whipple on it for an extra $4k. Just skeptical with long jevity with installing the supercharger. Also wondering if doing a prop change to a herring 5 blade?

Thanks for any help or input!!

I'd start with the Hardin Marine Stage 2. Installing a supercharger on your current setup will make a bunch more power which leads into other problems, ie be prepared to buy a new drive soon. You start chasing your tail on breaking parts.

I'm in the low 80's with 640hp in my 2005 29. But, dialing in the prop has/is challenging. I swapped my lower unit for a -1" IMCO shorty.

I have a 95 single step 29 with HP500's that I've rebuilt and added bigger cams, Dyno was 556HP with 610 torque. I'm turning 29 Hydromotive wheels and at 5200 running 81 on GPS. Just saying
