FINCHASER Posted May 9, 2020 Report Share Posted May 9, 2020 Anyone happen to have a manual (pdf) they are willing to share? Or any maintenance related tips for this motor? Ive found the T stats.... havent seen any outer anodes though but a large portion of the motor is concealed by the intakes on both side so wonder if there is any under them?

jh141 Posted May 9, 2020 Report Share Posted May 9, 2020 Is the F300 a 4.2 liter. Quote Link to comment Share on other sites More sharing options...
jh141 Posted May 9, 2020 Report Share Posted May 9, 2020 Just answered my own question. The F300 is a 4.2 liter, same as the VF 200-250 SHO. There are internal Anodes and manual says good for 500 hrs. Yamaha Tech told me most still look great after 1000 hrs. I have a hard copy service manual for my 200 SHO. nothing electronic.

jason p Posted May 9, 2020 Report Share Posted May 9, 2020 Get an electric vacuum pump to change the oil... pulling those mid-section panels is a PITA. There’s anodes all over the place on the motor looking at the manual (sorry no PDF) as stated above I’m not touching them until at least 1000 hours. I pulled all the internal anodes on my 115 at 500 and they all looked brand new, you could still read the part numbers cast on them. Quote Link to comment Share on other sites More sharing options...
FINCHASER Posted May 9, 2020 Author Report Share Posted May 9, 2020 Yea I already have a pump that I used on the last boat. When I said external I meant those anodes that are accessible externally... last F150 had 3 you could pull out to inspect / clean by just removing 1 bolt. Internal anodes require some engine disassembly Quote Link to comment Share on other sites More sharing options...
jh141 Posted May 9, 2020 Report Share Posted May 9, 2020 There are no easy to reach anodes like on the f150 Quote Link to comment Share on other sites More sharing options...
jason p Posted May 9, 2020 Report Share Posted May 9, 2020 Enjoy... #20-23 there’s two you can access and two under the valve cover I believe they’re the same anodes that we’re on the cylinder head of the F90-150s https://www.simyamaha.com/category_s/12913.htm?year=35&model=1529&part-category=27 Quote Link to comment Share on other sites More sharing options...
