3GM30 Manual -

Post by sforgey2 »

Anyone have a used 3GM30 Manual for sale?

I ended up repowering with a rebuilt one and dont have the manual. Runs great, will detail the expensive issues I ran into...but need a manual for now.

Thanks

My 2gm20 manual is on the boat but I think it covers 3gm20 as well. I can confirm that.

If so I could take it to Kinkos and copy it for you. Not sure how much that would cost these days but I would do it if you ran out of other options. I think the whole service manual is about 200 double sided pages plus a number of fold outs. I would also get a parts book, those are engine specific but absolutely invaluable because of the detailed breakdown drawings of each subsystem.

Over the years I have saved a kings ransom doing my own work on the engine and having these books was key.

Thanks so much.

I used mine for the old 3gmf all the time.


I can buy the PDF of the book and have it printed, so no worries. $26 on Etsy.

I have the hardcopies of the manuals but these are sweet! Thanks for posting the links. I am going to try to find the 2gmf parts book PDF. Coincidentally, after an abysmal performance in the latest Bay Area Vallejo 1/2 race I am dedicated to "deweighting" the boat. I have 100 pounds off so far and with these PDFs I can offload the hardcopy manuals for another three pound savings.

I am also having the bottom done after 4.5 years (yea, I know) and replacing my camber spar jib now that I finally know how the camberspar works thanks to this board.

I plan on destroying one of my chief rivals in the next race.... and yes, hope springs eternal...
