Volvo Penta 5.0 Issues ??

[gapple12]

Ok, just bought a 2002 Monterey 190 with a Volvo Penta 5.0 engine/ drive on it. Motor and boat only have 75 hours on it and the boat looks flawless. The previous owner used it maybe 5 times a year and had it winterized and maintained by a local boat mechanic. Boat looks absolutely flawless so i jumped on it. Here are a few issues i found today on first day out:

1) Motor doesn't seem to have a choke like my Nitro outboard by holding key in, therefor takes a minute to get it running. Is there anyway to choke these ?

2) Once i got it running, I put it in gear at lowest speed and motor wants to die, then give it gas and all is good. I didn't have this problem again making me think it just needed to warm up ? Bad or old gas ?

3) last issue was when running at full speed wide open for about a minute, I heard a beeping sound coming from the motor. Temp was about 150 and oil pressure looked fine. Any ideas ??

Thanks in advance to whom ever can help. I figured with the low hours and regular maintenance plus winterizing it would be a gem.

Is it carbed or injected?

The center of the throttle has a button, you can press that in and that will allow you to move the throttle without engaging the gearshift, push it in and move the throttle forward, then back to neutral, that will set your choke if it's carbed. If it's injected, no choke. Should start pretty quickly either way. Had it winterized, do you have a receipt of what was done? Might need plugs and the basic tuneup stuff. Regular maintenance means different things to different people. Did they just check the oil every season or did they change it? Hey it looks good, it'll go another year since we dont boat much............ So check all that yourself. You should let it warm up a bit, however it should go into gear idling cold and not stall. As for the beeping, dont know. Especially since you say it has good oil pressure and engine temp. If it's injected you will probably need to have it hooked to a scanner, and marine ones are different than their automotive counterparts.

Thanks for the reply gbeltran, the motor has a carb. I will try the button on the throttle, forgot I could do that. Ive been spoiled with a new Mercury outboard for the last few years that fires right up. I'm calling the boat doctor mechanic that did all the maintenance for it today to see if he can tell me what all was done. The guy I bought the boat from knows NOTHING about boats, but said to just call him. He would just call this boat mechanic out every end and beginning of the year and do what needed to be done. One thing that bothered me was when I pulled the plug yesterday, the boat drained about a gallon of water. The whole day on the lake we never took on ANY water so I'm hoping there is not a leak I just cant see. This could be the cause of my beeping alarm at full power as there may be a water leak in higher RPM situations. Impeller could need a change out.

Re: Volvo Penta 5.0 Issues ??

1) Choke it like gbeltran suggested and let it warm up. All the way forward and back sets the choke, then you'll need to leave it at high idle for a little bit to warm up, so use the throttle-only button for that.

2) All those carbs are different...mine wants to die if I shift with it cold too. Bad gas will give you a lot more problems than just that.

3)Next time you hear that beeping, go back there and check things out. Anything really hot? Check the exhaust risers and elbows, they have overheat alarms on them but no associated gauge to look at. You could just have a sensor that's starting to ground out.

How often are you or kids getting in and out of the boat? You'd be very surprised how quick dripping water adds up in the bilge. If your impeller is leaking you'll be able to see it pretty easily at the front of the engine, but it won't make an alarm sound if your temp is fine.

Well, we got in and out of the boat a handful of times swimming, so possibly that's why. Motor did seem to be pretty hot after running for a bit. Now, I found my depth gauge was not reading correctly, always reading between 13 and 14 feet no matter what. I know it has a shallow and a deep alarm on it( I never will understand a deep alarm), so next time out I'm going to see if it malfunctions at high speed and is sounding the alarm. Could be the whole issue, but the alarm sounded like it was coming from the motor area, not at the dash. Thanks for your help......

Re: Volvo Penta 5.0 Issues ??

Im curious how one runs this motor to wide open and can troubleshoot the alarm ? Can I use the motor flusher attached to the water intake and press throttle only button so the prop wont turn and go full power to make the alarm sound ? Not sure how I could do this test on the water while having the engine compartment open. Is the water hose enough water feed for this test ?

Re: Volvo Penta 5.0 Issues ??

No it is not recommended to run anything other than high idle while on the muffs, for a couple reasons:
1) The engine has no load on it
2) You will not have adequate water flow from a hose to cool the engine appropriately

I didn't think of the load from the prop, thanks for the reply !!! I plan on doing some troubleshooting this weekend. Going to pick up a good temp gun to see if something is getting hot after a full power run. Will an engine alarm sound from the engine area or will it come from the dash ?

Re: Volvo Penta 5.0 Issues ??

In my experience, they are located up around the dash area. Seems like the sound dampening features of engine hatches would render an alarm pretty useless back there especially while underway and/or with a radio on. It's the same screeching noise you hear when you turn the key to "on" but haven't started the engine yet. That's the oil pressure alarm letting you know you have no oil pressure (as expected).

Ok, thanks.....I do remember it coming from the dash, your right, no way you could hear that under the cover. Seemed like it was 2 beeps, then pause, 2 more beeps, pause and so on.

Re: Volvo Penta 5.0 Issues ??

Rain can fill up a bilge too while boat is in storage, I leave my plug out for that reason. Also to see the look on folks faces as water starts coming out of the bilge and onto the floor creeping toward them slowly and I yell "AUUgh we must be over Daveys Locker! Abandon ship!" Then guys jump in with their wallets still in their pockets and ladies run in circles screaming then I calmly yell out "I'll save us all! If I'm not back in 5 minutes, assume the worst!" Then dive in with the plug in my hand and stick it in under water then swim under the hull thumping it towards the bow which usually gets the women to jump in, voila! Wet T shirts. If it still is acting up then the choke isnt adjusted correctly. You should allow a minute of so of fast idle in the water before you put it in gear and back off the trailer. It should stay running. If not, something is wrong.

Now that is funny !!! I have left it out many times, once fishing during the winter and had to go in, not fun. As for the plug, I left it out this past trip until I went to put in on the ramp. This is why i was surprised to see water come out. I'm sure it was from my son going in and out of the boat wet swimming as well as my wife. I have a lot of things to check this coming trip to the lake.

Re: Volvo Penta 5.0 Issues ??

I have the same engine, about the same year. On issue no. 2, the prior owner told me that when starting it up cold, I should always wait until the temp needle came all the way up to normal. He said that otherwise, it will die when put in gear. I always wait at least 2 minutes before shoving off.

Re: Volvo Penta 5.0 Issues ??

His engine is carbureted, and therefore requires a different starting method than your fuel injected engine. That being said, if you can't put an efi engine into gear before being up to normal operating temp, it has a problem.
