No Oil Pressure(?)
Re: No Oil Pressure(?)
Update: My Cobalt's been in the shop since February 15th, so over a month. They've eliminated simple fixes like the sender, the oil pump, or other things. Their current analysis says it's a bearing that's preventing the pump from pumping. So the engine has to go out to a marine engine rebuilder to be taken apart and see how much damage this shot bearing has caused, and repair, rebuild, or replace all parts affected. No estimate on cost or timing, just "this will take some time and it's a major job". This engine was rebuilt by Jasper Marine just three years ago, probably hasn't got more than 20-30 hours on it.

Hate to hear, was hoping it would be an easier fix. Will Jasper help?

Re: No Oil Pressure(?)
Update: after one month in the shop I finally heard from the service manager that they had exhausted all options, and realized they needed a special tool to test the pump system (suspect somewhere in the drive system for the pump). They then came back and said probably a bearing, will need to send out to machine shop, hope engine is not ruined. The next day (today) I got a call saying they'd called all around, no one could even look at it for at least a month, so you have to replace the entire engine. $13,000 estimate P&L. I approved it because I've been 33 days without a boat during the most beautiful weather of the year and I have gone insane. Also, I have no choice.
PS: The engine that failed was a recently rebuilt engine from Jasper Marine ($14,000 P&L). It was installed in March 2021 following our hard freeze, so it was right at three years old and had maybe 25 hours on it. Jasper's warranty is two years. So now I'll have another rebuilt Jasper engine. However, this time I will drive it til I run out of gas money. If this new engine's as weak as the last one, at least it's going to fail during the warranty period.

Re: No Oil Pressure(?)
I would run the pi$$ out of it as it sounds like the failure in the other engine was likely a rebuild issue, just didn't show up in the warranty. Maybe you already have, but I would talk to Jasper about some consideration -- you are buying your second engine from them in what 3yrs? Maybe at least give you something for the old one - which they would likely fix and sell again.
I think you said insurance covered the first one - freeze damage - any help there with this one?
Honestly it would hurt me to dump that kind of $$ in an engine -- but if I had your boat with an 8.1 I probably would do it. they are not making those things anymore! Sure a new Cobalt you can get a 430hp 6.2, but it's not a big block like yours.
Hopefully a few nice days on the water will leave the sting of this your wake!

Re: No Oil Pressure(?)
Appreciate the comments, billk. So here's an update for you: I got the boat back with the new (rebuilt) Jasper Marine engine and it ran great - for about 5 hours. After carefully observing the break-in time and then running it around the lake at varying speeds I got a vicious knocking sound - about 5 hours into this new (rebuilt) motor. I called the shop and let them listen to the sound over my phone and they said bring it in right now. A week later they notified me: engine blown, sending off to Jasper, new one will be here in 3 weeks. So now I wait patiently for another Jasper Marine rebuilt engine to put into my Cobalt. And cross my fingers that third time's a charm.
This kind of information deserves a significant post of its own but I think I'll wait till I get my boat back

Re: No Oil Pressure(?)
That's terrible luck. I've heard good things about Jasper engines, but your string of bad luck makes me wonder how good their quality control really is, or if the installer's not doing the best job getting things set up right.

Re: No Oil Pressure(?)
I agree that Jasper should be looking at cutting you a break on the new engine, but I think I would expect the installer/reseller to be automatically advocating on your behalf with Jasper given the low hours on the last engine. Please keep us posted on how this resolves.groberts4 wrote: ↑Tue Mar 19, 2024 4:38 pm Update: after one month in the shop I finally heard from the service manager that they had exhausted all options, and realized they needed a special tool to test the pump system (suspect somewhere in the drive system for the pump).

Re: No Oil Pressure(?)
Not sure what happened to your first rebuild, and doubtful any one of us will, since it wasn't disassembled by your local shop. With the latest rebuild crapping out too, it makes me wonder if it's a rebuilt parts quality issue. Not quite the same, but similar, in that I know a lot of hobby or home engine builders are more frequently running into wiped cam lobes. This can be due to improper break in done when the engine is initially fired up, or just from a lack of quality materials used to build the camshafts. Either way, it seems to happen fairly frequently as of late.
Either way, you deserve some sort of compensation for the frequency of this problem, and how quickly it is happening (low hours). All of this together should show that it isn't you causing the issue, and it's either the shop installing, or the engine builder (rebuilders) themselves. Hopefully they get this settled for you before the season is over.

Re: No Oil Pressure(?)
Hey billk - I've got an update that will blow your mind: about a month ago the guys at Rinker finished swapping out the old engine, installed a new (Jasper Marine rebuilt) and I was a happy camper - for 5 hours of boating time. I minded the hours of break-in time, had some fun, and a couple of weeks after getting the "new" engine back it starting banging hard - like a push rod up against the valve cover or something. I played the soundtrack for the Rinker guys and they had me bring the boat right in. Their lead mechanic listened for about 5 seconds and shook his head, said "It's deep". Bottom line: another bad Jasper Marine engine. So now we have a NEW "new" one on order, will be here 5/21. So I'll be on my third Jasper Marine rebuilt Volvo Penta 8.1L in as many months. At least this time the replacement engine and labor is covered by the warranty.
Wish me luck.

Re: No Oil Pressure(?)
Any update? I'm looking at a 262 that has a new Jasper block (8.1 Gi), but has all of about 30 minutes of run time (and is outside of the warranty period.....long story). The new Jasper block was also an OEM replacement due to the freeze a few years ago.groberts4 wrote: ↑Mon May 20, 2024 2:37 pmgroberts4 wrote: ↑Wed May 15, 2024 4:03 pm Apologies all - For some reason when I pull up "Your Posts" I don't see any of your or my posts on this thread after March.

Re: No Oil Pressure(?)
We got the new Jasper motor in and it's been running very well. I've put about 10-12 hours on it since it came in - observed the break-in period and then giving it a real workout ever since. It runs very well, the exact same max speed as the last one that broke (55 mph). I'm taking it in this coming week for the 10-hour service ($912 - ouch!). So far so good.
