I recently acquired a 93 Bayliner 2452 with 5.0 two barrel. It seems to run very well, has great oil pressure and a closed cooling system.
Questions:
1. The closed cooling system had weak antifreeze to handle about 10 degrees F at best. I want it to handle Montana winters at minus 35 F. I took out all of the antifreeze in the resivoir and added straight stuff, about half gallon. I ran the boat for several hours, when I returned I tested the resivoir and it was strong enough to handle minuse 35,,,however,,,,did the antifreeze circulate when I ran the engine for several hours,,,, or did what I put in just sit there;;;;;;I don't understand the system well enough.
2. The heat exchanger is a pain to get too,,,long cylinder deep next to the floor and seems to have drain plugs on each end underneath, but, very tight.....is one end for antifreeze drain, and the other for raw water? Is there any easier way to drain either, if/when need be?
3. It has nice trim tabs,however, I'd like to add a set of the manual tabs towards the center of the boat to help lift and run on plane at lower rpms....I visited with the manufacturer and they seemed to think it'd do the trick...as you may know the 2452 is a lot of boat for the 5.0 and I'd like to give it added lift to plane and run slower without dropping back into the hole....anyone ever use both...I've never heard of it, but don't know why it would not work well...if not.
Thanks
