The time has come when I need to replace maifolds and engine mounts and most proberly hoses on my mercruiser. Also there is some general clean up and corosion repairs to be done. Alot of this work appears to be very labour intence therefor expencive. I consider myself to be reasonably mechanicly minded, have built a motor or two and done a few conversons of v8s to cruisers. I am considering undertaking this work myself to reduce costs and am wondering if this a wise way to go or would I be better off bitting the bullit and paying to have the work done and having the piece of mind that it was done by a pro.
