hey guys, read a bunch of good info here , thanks to those who take the time to post!
i have owned the ocean pro 115 since new and love it, best outboard for salt water i have ever owned , and i have had more than a few. still looks like new under the cover and that's something for a ocean going 25year old motor. coming from a auto mechanic background i do all of my own work and have the factory service and parts books.
as of now the motor is bone stock but due to age i went to premix a while back rather than putting out the dough for a new vro. i just felt i did not want to risk it any longer and have premixed most of my life. that being said the vro was flawless for many years.
now i am at the point where i want to do some more preventive maintenance , hose replacement ect, ect, so i am planing the delete the vro fuel pump and try and simplify the whole intake area a bit so i can see whats going on there more like the good old days of simple out boards.
sounds like some here (headhigh ) have done a vro and vapor pump delete. i already run a 10 micron spin on filter/ water separator so it seems doable at first look to me. although the fuel pump delete is straight forward i am not sure about the vapor separator , mechanically i see no issues other than maybe needing to make a bracket for the primer solenoid . i have to admit i dont really know why the vapor separator/ pump is used in the first place other than maybe to protect the vro pump or is it a smog device? never had one on any other outboard i have owned. the fuel vapor or air in the lines was just vented out through the float bowl vents. i guess it also prevents a air lock in the fuel pump but that has never been a issue for me in the past given the tank side system is vacuum leak free.
i have read a lot of factory service books , some really bad , some very good , and the omc book is about a b/b+ imo. i cant find any thing about testing the main bearing "vents" and check valves that are shown in the parts book. that is just 1 thing that comes up when i am trying to reverse engineer what to do w/ the vents ect at the vapor pump. i cant find any explanation or theory on some of the hoses that will need to be dealt with. if i know the theory is i can usually figure it out. on my motor both hoses going to the main bearings pass air both directions so if there are check valves there they dont work or i dont understand how they should work. the one caveat here is my hose diagram shows the lower main vent tees possibly and i did not plug the end at the balance tube.
any input or questions or answers to the long winded above greatly appreciated. headhigh, please jump in here!
