Gen 2 Alpha - Do you need to remove the engine to change trim pump hoses?

[San_Diego_SeaRay]

I'm asking for a friend so I don't have all the engine info. But on my Bravo setup I thought I remember that I could just remove the hydraulic manifold at the bottom of the transom assembly, unscrew the fittings then feed the hoses back into the engine bay and remove them from the trim pump. Then you could do the opposite to replace them.

A shop is telling my friend they need to pull the engine to do this repair on his Alpha Gen 2 setup. Does this sound right? Thx in advance.

EDIT for clarification: These are the black and grey trim pump hoses inside the engine bay, not the stainless steel ones that are on the outside of the boat.

On my gen 1, disconnect them from pump, take off bolts from exterior mounting plate and pull the hoses out of boat. Easy

The Alpha Gen.II is the same,....

Thanks guys. I appreciate the confirmation. This is a reputable shop that told him the engine had to be pulled so probably (hopefully) just some confusion between the parties. But I've relayed the message that no, it shouldn't have to be pulled.

Just for your entertainment I looked up some pictures.
As you see the hoses are running underneath the exhaust to this "distributor block" outside. If you remove this you can pull the hoses out if they are not fixed inside somewhere.
Sure it will be much more comfortable to replace the hoses with the engine removed but it is possible also with the engine in place. Maybe you could do it the same way as it is recommended for the shift wire and tie some robe to the hoses that you pull out together with them. So you can pull the new hoses in the same way.



This block has a little rubber plug in the midle that is very important.

You CAN change the hoses without pulling the engine, but when I do it, I pull the engine, it's a ton easier with the engine out of the way, and R&Ring an engine is quick enough.

Disconnect hoses at Trim motor and connect small rope(S) to their ends to use to pull new hoses back through. Disconnect at OD manifold and pull old hoses out until you see rope. You will use rope to help bring new hoses back to trim motor. If my memory serves me correctly, you will only be able to PUSH one new hose at a time (due to the lack of room) up and through the transom assembly. Then, pull rope until you can grab hose fitting.

UPDATE: Well I tried to do it this weekend and confirmed that you absolutely CAN do this without pulling the engine.

Some points to consider:

• The most difficult thing was trying to get the black and grey hoses off the manifold. We ended up cutting them off because my friend had bought new hoses anyway but I can imagine if that wasn't an option this could have been WAY more difficult. Even with flare nut wrenches the fittings didn't budge and there isn't a lot of room to work with. So we just cut them w. a sawzall. Someone who wants to re-use their hoses should have a propane torch or even better oxy/acetylene torch ready to heat and loosen fittings.
• As mentioned above, tie a string to each hose as you pull it out so that you can use the string to re-route the new hoses. This part wasn't hard.
• Also as mentioned above, once you have the first new hose routed back into place, you have to push that hose out towards the back of the boat just a bit so that the metal 90 degree fitting is completely out of the way of the 2nd hose. Then you can route 2nd hose in and push both 90 degree fittings into cavity at the same time.

Thanks everyone for your input. Was nice to know it could be done.
