I already have the volvo engine and sterndrive manuals for my 93 501B DP290, but they're the actual mechanic manuals from Volvo, and are not very descriptive. I have one for my OMC that I paid BIG bucks for, but it was fantansic when it came to directions and pictures, unlike these Volvo's. Can anyone suggest, or lead me too the best choice for the do it yourselfers for my unit. Thanks
