I pulled the trigger today...Cummins 6bta 370 with ZF 1.75:1 ordered. 454s coming out tmrw. I am going to have a bunch of questions so ill apoligize in advance. Does anyone have a picture of any stringer modifications they made prior to the new engine install? Whats the opinion of adding fuel polishing system? FrankP--thanks for the help with your local contact the local distributor came in to my yard at the same price point and they are the ones who "bless" the install for Warranty (and their technical guru has a Bert35 with 6BTA and will oversee the install..I thought it was prudent to make sure i had access to him..but i really appreciate your help.

Congrats. You've made a great choice that will greatly enhance your boating experience. Personally, I don't think you need a seperate fuel polishing system. Just keep spare filters on board (both racor and on engine). Just running the engines will polish the fuel.

How is their technical guru doing. I heard he was pretty sick. I hope this means good news as he is a great guy.

Congrats & good luck Robert, you've got a lot of work to do ! Rick Ticket 85 SF Merc 454 MPI's Falmouth, MA

I can't wait to hear about this... Take pictures, Keep receipts... share the details! Good luck!

You'll love those engines. I don't have a polishing system haven't seen the need for one. Like Doug says get some extra filters. I would install a high quality oil changing system. Buzz

So are you pulling out the rear bulkhead? Or pulling them through the door? What kind of stringer mods are necessary? Exhaust mods? Keeping the same size shafts?

Scott- RearBulkhead not a factor its and SF-- Im going to go with a larger Shaft diam 1.75…All new struts where put on about 3 years ago and If i recall correctly i might be able to accomidate the new 1.75 without booring out--- save me some bottemwork. DougL —what oil change System do you recommend? Charlie–Ive spoken with him and I believe his issues were dealt with. I am Keeping a running spreadsheet with all numbers ill share with all. As well as pictures. Any advice with selling my 454s-- they are in good shape (port runs perfect good compression in all cyl) (Starbrds in goood shape but needs a valve jobs-- already have heads off) 6month old Risers and Exhaust Mani...1400 hrs on both engs. Also have 2 1.5 inch Aqmt22 shafts (one 10 m old & one 3 yr old) Also two Nibral 23x26 3 blade (one 10 m old & one 3 yr old) All in perfect condition....

Robert, are you selling the props and shafts? If so how long are the shafts and what are you asking for the shafts and props? Buzz

Robert I think you mean Frank B. Our dog gone names are just too similar. At any rate, you will not need any stringer modifications other than just filling the old mount bracket holes with epoxy and cleaning it up for paint. Hopefully the yard won't try to tell you that you do. The job is very straight forward. You are going to be so happy with your boat and ease of maintenance.

Robert... check out the prices on these re-man 454's. I have kept this site handy in the event my STB finally dies... anyway it should give you an idea what they are worth..http://www.454mercruiser.com/index.html

Robert, I went with the Reverso GP - 3015 oil change system. I think I got it at the attached web-site. $396 sale price is pretty darn good. http://www.marine-electronics-unlimited ... riess.html

Sorry, it's $535 for the 5 valve system I got, mis-read the ad.

Oil change system is a must with 30+ quarts of oil coming out at each change.
