new boat owner couple 190 horizon questions

hellasnow · **Posted:** Wed Apr 23, 2008 2:34 pm

newb to the forum and owning a boat as well. last year was my first season with a 2000 190 horizon. had a blast and loved the boat.

1. i had a shop in town winterize the boat before she got put away. i'm heading to lake powell in late may and live in colorado. i have to go over vail pass and have been told by 90% of coloradans to drain the water out before going over the pass both ways. where are these located on the motor? and how many will there be?

2. should i fire it up at home the first time and buy the adapter to hook it up to the hose before putting it in the lake?

3. my wife and i have had the oil presure alarm beep at us a few times last year. it seems to happen when the boat is getting put in the water and is only idleing on the trailer still with the outdrive in. once it gets a little throtle it stops. then if i'm cruzing around a cove real slow for awhile it will sometimes (not always) beep at us. we do notice oil presure is low on the gauge as well but not burning any oil at all. ideas?

thanks for any and all input!

1. It would be a lot of trouble to get every bit of water out just to save 15-20 lbs.
2. I would make sure it starts & runs before hauling it to any lake, no matter how close.
3. Motor may be tired. If your oil level is where it should be, the only reason for low pressure is the pump. (since your temp wasn't mentioned)

Small block GM engines really don't require much oil pressure at low RPM.
How many hours does this boat have?

1. getting the water out of the motor is important due to the cold weather in colorado. going over the pass it could snow in the summer. wasn't really thinking about weight but wouldn't that be nice!!!

2. good call

3. the pressure gauge does drop down when this happens. as for temp it's been 8 months since i've been on it but from what i recall i don't remember temp being out of the norm and we do pay attention to the guages. i was hoping not to have to replace the pump. ideas on what that might run?

boat has 290hrs it ran really well last summer. with 2 of us on it we were around 47mph and thats at 5500'+

thanks for the reply

You really should get a Volvo manual if you are going to be draining this yourself. As a general rule, small block Chevies have 2 drains on each side of the block, one on each manifold, there is usually one on the power steering cooler (on many Volvos and OMCs, mounted on the rear of the engine, hard to get at). The raw water pump hose on the front of the engine should re removed and drained, same thing with the circulation pump (auto style water pump on the front of the engine).

The oil pressure issue, I can say that my 20 year old 4.3 idles (hot) at about 25 psi, runs at 55-65 or so, cold psi is higher. That is running straight 30 weight oil as recommended by OMC. You should check the oil level, make sure the oil filter is not leaking and verify that you are using the correct oil. I think Volvo specifies a straight 30 W synthetic.
Old school mechanics used to say small block Chevys needed 10 psi for each 1000 rpm of engine speed.

thanks all for your replies!

May sound obvious but did you check the dip stick with the boat level to see if there is enough oil in it ??
just a thought

i will defiantly triple check that ardy thanks for the thought, got me thinking am i checking the oil on the trailer only? but I've sworn I've checked it out on the water as well.

i went to the local dealer yesterday and had a long discussion about what it could be. turns out i'm putting straight volvo penta 30w synthetic instead of the marina that winterized it put 25w-30 in. i'm replacing the sensor that goes to the beep warning. then i hope it goes away. i really don't want it to be the oil pump that would be one hell of a job. i'm also putting in a impeller no clue when the previous owner did this.

thanks for the replies!

Am I mistaken, or have I read/heard/been told that mixing regular and synthetic can cause an oil pressure issue at low RPM's? Anyone want to verify that or correct me?

hellasnow · **Posted:** Wed Apr 30, 2008 1:58 pm

when i bought it i had the oil changed as well as when it got winterized last year. i found out when the marina that i bought it from winterized it for me they put 20w-30 in it, but i don't believe it to have ever been a mix. i guess my post could have been missleading stating i was adding 30w ontop of what was in there. i'm going to change the oil to VP 30w synthetic. i'm just trying to think of everything it could be.

thanks for the thought tho i'm just hoping it is oil and or sensor related.

I'm just worried i might have a bad pump at low RPM and i hear the motor has to come out for an oil pump fix, not wanting to go there!

pet575 · **Posted:** Wed Apr 30, 2008 2:04 pm

Can't blame you for not wanting to get into that. I wasn't sure your post said you had mixed the oils, was just throwing it out there as a possibility. Not sure how much "mixing" has to occur to make it happen. I seriously doubt that the remaining traces after a change would cause it. But, I'm not sure about that either.

After typing my last message, I remember a conversation I had with my dealer's service guys when I went in for some warranty work. They found both regular and synthetic quarts in one of my storage hatches, and were making sure I wasn't mixing because it was said to cause low RPM pressure problems.

hellasnow · **Posted:** Wed Apr 30, 2008 2:11 pm

thanks pet575, i can see mixing effecting it. i'm changing it to what it calls for and putting a sensor in to try and start eliminating every possibility, i hate these types of problems thanks for the help.

Check the connector before you go replacing the whole sensor sending unit. I had a gauge problem with my oil pressure gauge bottoming out all time (but no beeping) when it was brand new last year (this is what led to the questions mentioned above about mixing oil). The dealer found that the connector to the sending unit was bad, and that it supposedly fixed the problem (I had it done over the winter, so no use yet to verify). Might check there first and hopefully save yourself a little money.

Good luck.

hellasnow,

Has the beeping gone away after your fixes? What exactly did you do and if you don’t mind, how much did the replacements/service cost (assuming you took it to shop)
I have a 01 180 horizon with the 5.0Gi. Just started getting the same oil alarm when at low rpms. Oil gauge works fine ( I have one of those crappy VDO clusters) and engine temp has been normal. I had the oil changed at in Feb (about 5 hours ago) and I found out they used 10-30 weight oil. I assumed they used OEM spec oil (30W volvo oil), but they didn’t. The four winns dealer, which wasn’t the shop that did the oil change, said they don’t use 10-30 or 30W, they use 20-40 (found that it is best for pacific northwest conditions. I am wondering if changing oil weights is really going to help, and should I go back to the Volvo 30W?

Boat has 99 hours on it, has never had any problems, but I am not sure if the dealer has the problem figured out. I guess I will know when they give it back to me in a few days.

Thanks, CBW
