Looking for some data to help plan for winterizing my 87 340 express with 454 crusaders. Have always serviced my own boats, this one is new to me this season. All previous boats have been small block I/O's or inboards. First time with big blocks, and first time with big exhaust baffles.
Following is my plan:
Following is my plan:
- Drain blocks and manifolds
- Place collection tub with recirculating pump under exhaust ports
- Connect hose from recirculating pump to raw water hose intake after strainer
- Run engine circulating anti freeze, fog, shut down!
- Do people use the -50 antifreeze (pink) or -100 (blue)? I live in the upper Midwest….
- How many gallons will the block and exhaust baffles hold?
- Do you store with block full or drained?
