I just ordered manifolds off of a fresh water 2005 fx ho has 60E stamped on it looks the same. I could jb weld but to be honest I never wanna pull the motor again lol I will also keep a eye on oil on second engine and check the manifolds on that one at the end of season I pressurized it and it passed oil looks good for now.Your part number is 60E-14610-00-94. Check part through YamahaSportsPlaza.com for example. I would try filling crevasses with JB-Weld if you cannot find part at your price.
Yea will keep them for sure wonder if someone who welds aluminum could fix em.Hang on to old manifolds. At some point, you may find them of some value. Hope all goes well.
I hook compressed air into the water inlet and when the 1 line is on the big rubber boot Air comes out of whatever cylinders exhaust valve is open. The other engine does not do this so from what i can tell thats how water gets in my oilWhat do you mean by "air blows out of cylinders?"
Welp all back together same issue still looked at and tested the exhaust 100x times cant be a exhaust issue I am at a loss i put air in system air comers out 1 cylinder for example depending upon position engine it can come out each cylinder only 1 at a time tho I assume i have a crack in the head or block somewhere just odd to me no compression loss. ALSO ON A SIDE NOTE the pressure control valve that sits on the block is it suppose to be open or closed? rn nothing flows past it wondering if i have backpressure issue but not sure how it works.@Brad_Ct has replaced some seals in the exhaust system that were problematic. Others have found small holes when closely inspecting the exhaust manifolds.
