Thread: 525 SC 400 Hour Service

Hello All, Have a 1995 Fountain 27 Fever with a 525SC. The clock shows 400 ours and I am doing my winterizing now and was wondering if there was anything else I needed to do to the Engine other than drain and change the fluids and plugs? I think I headr somewhere along the way to check the valve clearance at 400 hours but not sure where or if it was a credible source. The motor starts, idles and runs strong. 76mph on the GPS so no indications...

yep, look at the valve springs and maybe do a leakdown,(i would consider swapping springs with those hrs). I have a pair in a 38 Donzi and they have been very trouble free with 260hrs. You mentioned drain the blocks i assume you are also topping them off with a marine storage antifreeze? The corrosion protection is very important. Keep an eye on the blower snout bearings and seals, i had heard with the Weiand they can have some minor issues.

Have a leak down test done. For the most accurate results, have it done on a warm engine. With 400hrs, it needs to be checked. Probably time for a valve job, springs and head gaskets. The springs are not a huge issue on 525SC's since they use a relatively low lift flat tappet cam. Also, it might be time to have the supercharger gone through and replace the bearings. How often do you change the SC lube???? Change the fuel pump lube as...
