Twin 350's, Trim issue

[Dobb15]

I have twin 350's which don't seem to trim at the same rate, and was wondering what was involved it installing one of those bars between the motors?? also is there a setting to adjust the trim settings??

Just measure the distance between the 2 drives on the front knife edge above the nose and the rear knife edge above the prop and adjust accordingly. I don't know if you think that bar will make the drives trim together but it won't. Only thing that is adjustable is the up limit switch. I don't think there is anything you can do to make them trim perfectly together. One of the pumps may work better than the other or the cylinders on one of the drives may go up easier than the other.

Dobb, the tie bar you mentioned will only keep both outdrives parallel to each other for running even distance apart. The difference in the trim motors can be a lot of things, oil thickness, motor speed, wire connections, different wire resistance, trim cyls, single solonids vs double, or the pumps themselves. I have twins and one pump is slower than the other. I do know if both pumps are exactly the same, wireing and everything and its very involved and only an experienced machanic should attempt this as I am. Those pumps on the up side generate 2500 to 3000psi, inside the pump resevour there are four adjustment screws for pressure and relief, the pressure tool is available. This can be a very tedious operation and on the bench is a must. If both pressures are made the same it will probably cure the problem. I have tried to get the information on the adjustment and no luck, I hope this info helps Buz
