Mercury 1994 2.0L 150 (continued)

[Glastron1987]

Carbs and fuel pump rebuilt, and fuel system hoses pretty much all set.

Now looking at re-hooking up the bleed lines. From the diagram it looks like transfer ports connect to the crankcase valves as follows:
2 to 6
4 to 1
6 to 3
1 to 4
3 to 5
5 to 2

This all makes sense to me as they are all 3 cylinders away from each other except for 2 to 6 and 3 to 5 which seem to be switched. Is there a reason for this or am I looking at the diagram wrong?

It all makes sense to me except why doesn't port 2 go to #5 intake instead of 6, and port 3 go to #6 intake instead of 5? The rest are spread 3 apart.

[Glastron1987]

Got my bleed lines all set. Still don't understand why 2 goes to 6 and 3 goes to 5 instead of 2 to 5 nd 3 to 6, but that's how the diagram shows it so that's the way it goes.

Now ready to wire up my power trim. The motor originally came with a 3-wire system, but after messing that up (not entirely my fault) I replaced it with a 2-wire system.

Instead of the two relays and such, anyone know what parts I need to replace that for the 2-wire system? Must be some sort of different connections.

[Glastron1987]

I guess the 3-wire has selonoids and I have to replace them with relays.

Correct. I recently did the same.

[Glastron1987]

Anyone have a photo from the back of the engine showing how the 2-wire relays mount to the plate between the coils/heads. Having trouble figuring on which holes to use that keep them and the wires neatly positioned.

Hurry up and finish it !!

Oh you want to race me too

So hows the build comin along , will it make it for a maiden voyage b4 winter?

[Glastron1987]

The main things left now are stator, switch boxes, flywheel, and lower unit before I fire it up and mount it. I am quite hopeful for a voyage before winter. Away for a few days. But getting excited. Have nearly all the parts to finish except the stator. Want yo go new on that but boy are they expensive.

[Glastron1987]

Anybody have any clue what this hose should connect to and/or what it's function is? It's the (jaggedly cut) hose just below the starter and looks like it comes from the front half of the motor. Another motor I looked at just had a brass plug in its place.

That hose would go to your remote oil tank to pressure it up to fill tank located on motor. Will not be used if oil injection is deleted. Best to remove check valve and plug like other motor if not using oil injection

Excellent, thanks. So many parts not needed without the oil injection. Maybe I'll take a photo of them all some time.

Ya it sure lightens the load!

[Glastron1987]

Here's a photo of all the oil injection parts that are no longer needed after the system has been deleted. This will be how I'll be running my second boat. I do have to add that my first boat has been running with oil injection for 31 years without incident, but deleting it on the second boat sure makes for a less complicated piece of machinery.

Got it plugged now, thanks.
