hey guys! I'm looking to purchase a larger boat with 588 cubic blower motors and #6 wet drives. I understand with larger boats comes more expensive parts etc. I'm wondering what the maintenance schedule is on wet #6 drives ( what oil do you prefer to run and how often do you change it). Also same with the motors what do you guys do to keep your motors healthy thru out the season. example: plugs, top end adjustments, oils trying to figure out a maintenance schedule on my own so i do not need to constantly have the boat at a shop. thank you for your time -Joe

Bigger faster boats especially with more power just simply cost a lot more than we all expect on a yearly basis. Obviously keeping up on maintenance helps but it still won't keep you out of the shop because high performance parts just don't last.
Plan on 10s of thousands in rebuilds/freshening every season.
Most likely the engines drives and trans are NOT in as good of shape as you hope when buying any used boat so be prepared for unexpected failures.
Depending on power levels and build details here's a general idea.
Expect to freshen the top ends every 100-200 hours
Bottom ends 200-400 hours
Drives 100-200
Trans 200
Oil changes and basic maintenance wont do much to prevent the valvetrain from wearing out....
Every fall you should do a leak down and compression test tracking your numbers in Hope's of catching worn out items before they break and cause more problems.
Pressure test exhaust yearly also.
Need engine build specs but most likely any 50wt that makes you feel warm and fuzzy changed about every 20hrs with any quality filter no need for a racing filter they don't filter as well.
Amsoil severe gear in 5 gallon pails work nice in the drives.
If it was me I'd buy less boat so you can afford to pay someone to help maintain it let alone afford the cost of ownership.
Good luck keep us updated!

completely understand that this is a serious money game thank you for the heads up. I'm trying to figure out maintenance and cost before i purchase. i don't mind going to a shop or engine shop if need be, but i actually really enjoy wrenching on my own boats . Iv owned a number of boats but nothing with 6's or a blower so this is an eye opener. I'm gonna do research on parts and everything mentioned above. i personally own a high end motorcycle and race car shop in nj so i have the tools and resources to pull engines etc. only thing i will not be touching is the bottom end and machining if need be so that should save some $$$

just got off the phone with the owner of the boat everything was refreshed and has zero hours. motors also have been turned down to 850hp at only 5 psi so that is a plus gonna continue to dig appreciate the help!

Can we have more info of the boat in question? Maybe pics or more details or the listing ad. Not for trying to steal it our from you. But their is a lot of knowledgeable people here that I’m pretty sure someone here may know the story or stories behind the boat in question. And they may have a little more insight for you. Just a thought.

its the small things that lead to trouble.....keep the water pump impellers fresh (i like the softer globe brand) new belts and hoses glue and safety wire the raw water intake line the pressure can exceed hundreds of pounds at speed.....another huge one in intercooler cores have a 2-3 year life and that's according to superchiller it is easy to test and inspect do it often! mobile one 20-50 V twin is the gold standard for anything with a blower keep it timed and lots of clean fresh fuel a little baby powder on the blower belt increases its life and the pulleys run cooler
