anyone know what gauge wire an 89 prostar would have to the battery? I need to order new terminals and the boat is out at the lakehouse so I cannot look.

Upgrade while you are in there! WWW.Genuinedealz.com has great prices on top of the line marine grade wire and connectors, and everything you need.

My 1990 had all common automotive grade thick strand copper. I went up to 00 thins strand tinned copper with marine grade connectors and mil spec self sealing shrink tube, and the automatic battery isolating relay setup.

Matt's on to something. 20+ year old battery cables probably just need replaced. Especially in a boat, wet environment and every ounce of battery juice counts.
