Help needed 2006 220 OIL Pressure heading to the lake in the morning.

[sjames]

I need soem advice after service my techs told me they noticed the oil pressure gauge is not working but the digital gauge reads 45lbs at idle.

The red light is also on even when I go above 1200 RPM. Headed to the lake in the morning and hoping this is the sending unit. The weird thing is as I rev up the gauge go more negative like it is running backwards?

Probably two red lights on your boat - the engine warning indicator (big one) and the V-drive oil pressure light (little one - with sign saying "should go off above 1200 RPM). This only applies if you have the Walters v-drive which I think your boat has.

The oil pressure gauges (digital and analog I guess) read the engine oil pressure. Sounds like the analog one has gone bad. If the digital one is reading 45 psi at idle, then you probably have plenty of engine oil pressure.

The small light for the v-drive will stay on past 1200 rpm if the v-drive is not turning (transmission in neutral). It will also stay lit in gear up to 1200 rpm because it is not turning fast enough to make enough pressure to turn off the light. Idling around the lake slow (under 1200 rpm) with the light on does not hurt the v-drive. When you are in gear and the engine is turning 1200 rpm or more the light should turn off or your v-drive is most likely low on oil. It has a dipstick that is easy to check.

P.S. probably don't run the boat in gear on the trailer unless you are spraying ample water on the cutless (strut) bushing/bearing to lubricate it or it may wear out prematurely.

EDIT: Sorry, just saw your picture, yes - that is the v-drive light and all of the above applies.

Thanks I realized that later. I bout the sending unit hope that fixes it

Ok bought a pressure sender and it it not the right one my 2006 I guess has the standard top threaded connection not the newer connector.

Gauge reads sometimes and has no light when I illuminate the dash at night.

The V drive was out of fluid so the light did stay on and I added 30W SAE to get the light out.

Good thing you checked the v-drive. Sometimes they leak from the gaskets, sometimes the seals. I don't know how far they will go before they seize up from no oil.

As long as you have never hit any underwater object (bent prop or shaft), it should not be damage at the back of the v-drive causing a leak. It might be worth it to check the coupler alignment at the v-drive. Lots of threads on how to do this on here and over at ccf.com and even youtube videos. Since it's a v-drive it's really a pain the neck to get to. However, bad alignment can cause seals/bearings to fail on the back of the v-drive among other problems.

You might open up the dash and check all of the wiring for the gauges. You might find that there is a loose/corroded connection. These boats often vibrate loose or corrode the gauge connections. While you are there, you can check all of the connections for soundness.
