Seacraft06 Posted June 4, 2017 Report Share Posted June 4, 2017 The SeaStar HC5358 on my 2005 20 Pathfinder wtih 2010 150 Yamaha four stroke started leaking. The rod is pitted. The motor is mounted all the way down and it is a real PITA to get off. I am going to order a new cylinder but not sure which one I should get. The HC5358 or the HC5345? To my understanding the HC5358 is only needed with twins. However, I also read where the HC5358 is needed if the motor is mounted low? So I am stuck. HC5345 or HC5358? Also if anyone has any pointers on how to get the support bars free? There is not much room to work with. Link to comment Share on other sites More sharing options...
FunFlatsFishing Posted June 4, 2017 Report Share Posted June 4, 2017 You may need to heat it up with a torch or buy a gear puller from harbor freight. They can can be a real pain to remove the horn. The good news is you only need to get one off. https://t.harborfreight.com/automotive-motorcycle/pullers/three-jaw-puller-set-3-pc-69105.html Link to comment Share on other sites More sharing options...
hurricane Posted June 4, 2017 Report Share Posted June 4, 2017 You can rebuild it or have it rebuilt. Might be an option cheaper than a new one, and you won't have to worry about part number. Link to comment Share on other sites More sharing options...
FunFlatsFishing Posted June 5, 2017 Report Share Posted June 5, 2017 The issue is that chrome rod is very difficult to find. The seals/end caps are easy to replace. There was a place in Tampa that worked on them but the guy passed away. Now it has to be mailed to Jacksonville. Link to comment Share on other sites More sharing options...
gambler1 Posted June 5, 2017 Report Share Posted June 5, 2017 The 5345 is what you need. They also make a 6345 for high performance, but the 5345 will be more than enough for your application. Link to comment Share on other sites More sharing options...
gambler1 Posted June 5, 2017 Report Share Posted June 5, 2017 I retract my comment on the 5345, I just noticed you do not have a hydraulic jackplate to raise motor. I would call the MBG and seastar for advice Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted June 5, 2017 Report Share Posted June 5, 2017 Was watching that boat repair TV show, you know the show where the fat guy with a beard shows how to fix stuff. Anyway one of the sponsors is a certified Sea-Star repair/rebuild shop in Venice, Fl. http://www.boatsteeringrebuilders.com/ Link to comment Share on other sites More sharing options...
General disarray Posted July 7, 2017 Report Share Posted July 7, 2017 Resurrecting a semi old thread. I am about to do the same thing. Is there enough room to pull the support rod? It doesn't seem like it - mine looks like the motor would have to be lifted out of the well to pull it? any experience? Link to comment Share on other sites More sharing options...
RodWorks Posted July 8, 2017 Report Share Posted July 8, 2017 If your just replacing the seals on the Seastar you don't need to pull the support rod out. Just pull the ears of both ends which takes a two jaw gear puller. Link to comment Share on other sites More sharing options...

mustang190 Posted July 9, 2017 Report Share Posted July 9, 2017 I had to replace the same exact one on my 150. Use the Seastar 5345-3. It's not hard to remove and replace. Spray it real good with some penetrating oil and just remove the ends. Don;t worry about dinging the anything, your going to replace it all with the new kit. Just be sure to use the grounding cable that comes with the new one,the old one did not have one I bet thus causing the corrosion problems. Find a stainless steel metric zirk fitting to use on the motor mount. It is in the instructions. Link to comment Share on other sites More sharing options...
