Let me start by saying this forum is great and I'm new to boating. I have owned my boat for six weeks now.
My question, is the Manual #7 the correct for the following:
1991 Glasstream 180 SE
4.3L mercruiser, serial #OD516564.
I'm thinking its right but received a "operation and maintenance manual" (1990, Brunswick Corportion 90-12546910 790) from the previous owner, that states in the specifications that the HP is 155. Looking through manual #7 the serial number appears to be covered, but the description for the HP doesn't. Also looking through service manual #25 it appears that one covers the serial number too. Am I on the right track here?
Thanks in advance!!

#7 is the manual you want, #25 is the Vortech engine with balance shaft, yours isn't Vortec, and you don't have a balance shaft.
There is no such thing as a 155hp 4.3 engine. Probably a misprint in the old owners manual. No way of updating them.
