Introduction

So because my IPS's were Gen A there were things that needed to be done, recommended by Volvo, to extend life. I believe this included Oil Cooler lines, new clutches, and on one of my units I also had to replace the prop shaft since it was bent. The good thing is that I identified all fo these things, me researching and the surveyor I had before I purchased the boat, therefore the seller picked up most of this cost. Some of the work, like clutch pack replacements, were due to the hours being at 1000. I think replacing those is part of the 1000 hour service. I ate I think 2k of what would have been 10k of cost back in 2012, the seller paid for the rest. I think there was one or two other things our Volvo IPS vendor did to those A units to make them really be at the spec of IPS B or C units I think, but it's worth researching if you have IPS A and haven't had anything done to them yet.

Bottom paint rubbing off where the IPS's turn should not really be a concern. My bottom paint rubbed off pretty evenly through a season on both drives. Your uneven could be an alignment issue or simply that drive been used more at those angles. Which would depending on how the previous owner used the boat. Maybe they always docked one way vs the other, or perhaps always turned and backed into their slip a certain way and maybe didn't use the boat enough elsewhere to even the wear. Alignment should be good if you boat tracks straight at speed. if you see it driving one way or the other at speed with the steering wheel centered, you should have alignment looked at.

when we got our boat, I think I used the propane grill once and was freaked out about propane sinking into the hull and causing an explosion that I simply decided to bite the bullet and replace it. The work was fairly easy in pulling out the old one and wiring the new Kenyon into the switch plate that was there under the grill on my boat. So no real hard wiring necessary. The biggest issue is that the Gas grill is larger than the frame of the Kenyon so I had to do something to make the opening smaller. What I ended up doing was getting a frame made by CutToSizeMetal.com in Stainless to support the Kenyon. Picture below. I simply measured what I needed to cover the existing opening with about a half inch all around and then had CutToSize cut that plate out of Stainless and cut the opening in the middle to the Kenyon spec. Worked and looked great. The only issue I ran into is that the lower right corner of the frame was very close to the lid that closes over the grill area. I was able to position things fine though as you'll see in the picture. The other benefit of the electric grill is you can use it in Marinas! Clearly you need to run the gene at anchor to use it, but we never had an issue with that and the Kenyon is great. I would buy one with a free standing cover, for cooking like an oven. My wife even made pizzas on the thing at anchor.

The other thing I would recommend for cooking on board is getting an single burner electric induction cooker. With the right pots, my wife could almost cook anything on that, and even out by the grill and it was quick. The Kenyon dual burner below was simply way to slow to cook. After half a summer we never used the cooktop under the corian and simply used the induction cooktop all the time.

The Fusion upgrade wasn't hard as the it simply went into the spot for the old Clarion and I positioned the amp in that cabinet under the sink as well. The overall upgrade was outstanding and I kept the white 6x9 speakers Kenwoods I think, that were in the boat originally. 5 years ago the Fusions didn't come with Bluetooth in the box, I simply added an adapter. I know that comes in the box today.

The the Auto Trim tabs were $300 I think and I installed them myself. Simply mounted the electronic brain behind the GPS under the helm and wired that up to the stock Bennet trim switch. I also had to put another unit at the control box at the transom of the boat, but it was simply mount it and connect 4 wires if I remember right. To be honest this was the biggest upgrade to me of everything I did. So much so I had these installed on the 33 OBX. On the OBX it's a different system, but what I found with the 4460 is that with the IPS setup and no tunnels under the boat, people moving around on the boat greatly affected its running attitude at cruise. I was constantly fiddling with the Bennet controls. Once I installed the Auto trim, I never had to touch the.controls again. The boat was always at the right running attitude.

As for the System in the cabin, I started to replace the TV with a newer flat screen since I tended to run into the existing TV some times walking out of the cabin since it stuck out so far. Lots of wiring behind cabinetry, ceiling and walls. To be honest I could figure out how to pull out the old TV electric hook up to get to that corner behind the microwave. I could have run cabling on top of the walls or ceiling but I didn't want to do that. So I gave up, always said it was going to be a winter project, since I started it midsummer and didn't want to tear the boat apart so much, but never got to it.

So I looked behind the Yamaha once and how to get to that cabling depends on where your microwave is. If your Microwave is in the corner left of the dual burner, you can get back there somewhat by pulling out the drawer to the right of the sink, but to really do a replacement I think you'd have to pull the fridge out completely. Probably not super difficult, but that would give you easier access to that wiring.

Tom, did you try to post pictures? A big round negative sign shows up below your post? Sounds like you have done a lot of work and investigating!You are doing great!

With our 2001 4160 she is still doing great, lots of maintenance, replaced pumps, halogen to LED bulbs, chep Kenwood audio to a Fusion Bluetooth capable head unit, new JL Audio 7.7's in the radar arch, 4X Klipsch 6.5" 2 way outdoor bracket mounted speakers mounted to underside of arch, a new JL Audio 4X 150 watt RMS amp for deck speakers, and just installed a JL Audio 12" infinite baffle marine sub with self made 1/2" thick sea board , and new JL Audio JX 1000/1 rms sub amp. I enjoy good music even though I am 71, younger sons don't like my music , kids (37 and 39 years old) ! With many years of both designing and building home audio speakers and buying a lot of cheap marine speakers I have to love the JL Audio marine stuff, little pricey but worth the money!
I previously posted a 4 page word dock with everything I have done to the 4160, if anybody is interested in a copy I would be glad to re post the file. I am pretty anal regarding recording everything done, wht what done/used, etc.

So I added attachments on this post for the pictures.   Trying to see if this works.    Its really strange that I can see the pictures in my post, so it must be a permissions issue I can't seem to figure out.

 ,Yes, pictures are here now? What did you finally do to get the pic's attached to the post?

there seems to be two options to post pictures.  Put a link to a site that host the pics or add them as attachments.     Originally, I added the pics with the link approach, using the 7th icon from the right from the icons at the top of the add post screen.    This is how the very first post was done at the top of the thread.     When I did this right after I posted I could see the pictures.    The were being served from Google Pictures.    Eventhough the pictures original showed for me in that first post right after posting, now in my view on that first post the pictures aren't showing only a rectangle with a blue square and a ? in the middle shows.    But if I right click on that question mark and click on open image in new tab or browser window I can see the image.   I'm interested in understanding if the same thing happens for you guys.  

When I added the post at the bottom responding to the picture not showing via the link method, I noticed the "Add Attachment" button on the top right of the thread editor window and used that approach and simply pushed the picture up to the forum.   

Guess I am nuts as well as my documents are involved but setup differently than yours.  I have a winterizing parts listing, a maintenance log broken out by engine, generator, boat, etc. and a checklist for winterizing / maintenance.  Here is my checklist for your review as well - Regal 3860 Winterizing Checklist.pdf (407.81 KB)
