belt replacement

Hello, How can i replace the belt on my 3.0 Mercruiser engine without taking it some where and having it done? Looks like the engine has to be lifted up in the front to do so. Thought about removing the two bolts that anchor the mount to the floor and having some one lever it up while slipping the new belt under the mount. Will this work, without damaging the point used to lever from? Thanks, Don Reed

Hello: Don

Assumption made is the engine has one belt (serpentine belt) and not multiple belts. Also, there is an engine support mounting bracket which the belt cannot be removed without removing the support first.

If the above is correct, than yes, the engine mount bracket has to be removed first, allowing access to remove the old belt and install the new belt(s).

An engine lifting device must be used. Commonly referred to as a "Cheery Picker" is used. The cherry picker can be rented at local rental yards. Engine have large eye loops premounted at specific points for the purpose of lifting the engines.

Chains are used with the lifting device. The chains have hooks which connect to the lifting eye lets and the cherry picker has a center single mounted hook to fasten the chain to.

The engines mount bracket bolts must be removed prior to lifting. Whether or not any rear engine mounting bolts must be either removed or loosened depends upon where they are located.

Usually but not always, slightly raising the front of the engine just enough to slip off the old belt and install a new belt does not always require removing or lossening any rear engine mounts.

Much depends upon that specific engines mounting system. May be a good idea to check with any engine mechanic. Auto mechanics or other boat owners whom work on their own boats are also familar with the process of lifting engines just enough to replace belts.

when u change the belt, slip another one in there & secure it with a plactic wire tie. that way if u ever need to change the belt again u won't need to go thru all this trouble. just make u sure u secure it well, so it doesn't get caught up in any pulleys. good luck.
