Well no Prestolite available to rebuild. Boating season will be over soon here in Ontario Canada.Im taking a chance on this but it is a complete unit motor resevior & valve body. It is an Arrowhead product that was ready available. Not my preferred choice but don't want to wait 2 to 3 weeks for shipping & customs coming from the States. It comes with a 1 yr warranty and bought it from a dealer who has had all success with them this summer. At least it's sealed & plug & play. I plan to install it today. Will keep u posted on how it goes. If it works the other CB is going back. I truly appreciative everyone's input on this topic, it has been most helpful.
