Re: could someone please help me find a manual
The only manuals that are supplied with boats come from the manufacturers of the radio, depth finders, locators, gps, and other accessories. The manufacturer of the boat has no idea what engine will be installed on it so they don't need to cover the engine. Their manual therefore is worthless collection of paper with what should be obvious safety related information. You need to order a factory service and/or operators manual for the engine from a dealer that sells that brand of engine, or there are a number of after market service manuals such as Clymer and Seloc but these tend to cover a range of engines so they are not as convenient or accurate as the factory manuals.
