Official 390 E.C. Thread

I never taken an infared reading but according to the water temp gauges on my 454's the port side runs 175 and the starbord runs 160. SeaRay put me in touch with a guy named Rocky at Mercrusier and he said 170 to 180 is fine for the big blocks. That was 10 years ago and I have had no issues.

Thanks for the info. That is very good to know. I was concerned with my motor running that hot.

I'm still wondering if the exhaust manifolds should be 140-150....

Ken, I'd like to do the same modification. Are you referring to the "golden balls"? Do they fit on our shifter??? ...and, where did you buy them?

Thank you

I don't know if they fit our shifter handles Pietro because I cannot seem to remove the plastic tee handles. I removed the screws, but that is as far as I can get. I thought that they might unscrew, but they don't want to budge. I was hoping that somebody would be able to offer some advice about this. I saw the gold knobs in a local chandelery & I think that I saw them on Ebay last year.

I want to change out all of my plastic & rubber windshield trims & screw caps this winter. I printed sheets from Taylor-made last year that showed all of their profiles for my boat, but I can't seem to find it. I think that I have it saved to "my favourites" on my other laptop. I think that I read somewhere that there is another company that supplies the same trims for less money than Taylor-made, so I will have to do some searches on that as well. I am going to remove the side windows, re-bed them and install all new gaskets and screw cap trims as well.

Hello all! I'm just wondering if anyone can tell me where I might find an original stock seat for a 1988 390 E.C. (drivers seat). Any advice would be greatly appreciated. I purchased the boat this summer and the previous owner had replaced the original stock seat with a much shorter, odd looking one. The colors don't need to match as I am recovering all of the seats this winter. Not sure where to start looking. Any advice would be greatly appreciated!

Similar to MinnesotaJims question above - for those who have had to replace/rebuild their cockpit helm and co-pilot seats due to rot, is there a company out there that makes replacements? Does anyone have recommendations on companies that may have templates? Or should I just look for a fiberglass marine shop to do the work?

Currently looking at a boat for sale that does not have the stock seats (no storage underneath) and would like to return it to the stock look if I decide to put in an offer. Thanks.

Can somebody point me in the right direction for aftermarket exhaust screens for my boat? I am concerned about muskrats sinking my boat.

Paul on Jackie JV had some custom made for his 560. If you PM him I am sure he can let you know who made them and how much $.

I just re bedded the side windows on my 86 390. I thought it would be a massive job, was nothing to it. On the port side the previous owner did use 3m 4200 on the very forward section of the window, so getting that off took the most time. I also took the time to polish the aluminum frames while I had them off the boat. Very easy job and ohh what a wonderful life it is when your boat is not raining inside

fyi

P.S if you want the pics she sent let me know and I will post those also.

Here's what i found on that windshield. I have also attached pictures of each

On the main windshield we used
Screw Cover 8338920 $3.16 per foot comes in 12' sections
Glazing vinyl 8337920 $2.61 per foot
Hinge cover 8229900 $2.28 per foot
Wire track 8233230 $2.18 per foot

On the side windows
Glazing Vinyl 8337920 $2.61 per foot

Screw Cover 8338950 $2.61 per foot comes in 11' sections

With all due respect, your mechanic is wrong about this. There are many “marine” filters that are junk same as auto filters. Some WIX filters have bypass as high as 23psi. When I choose a filter I do it based on internal construction. You want a filter that is built well, i.e. that the pleating is even and consistent in spacing, and that the bypass valve is at the top of the filter and not the bottom. With bypass valves at the bottom of the filter, all the oil that is bypassed passes over the outside of the filter media on its way through the filter, potentially picking up solids off the filter media. I don’t care who makes the filter or for what it is built as long as it is well built.

I just bought my 1988 390 express cruiser 2 months ago and figured that I'd save some money and change the oil myself. I purchased a jabsco motorized oil pump and removed the oil through the dipstick tube (was informed this was easiest and cleanest way to change the oil). Unfortunately I was only able to remove about 3 qts per motor, according to my manual the 7.4 L motors should have had at least 6 qts to remove. Has anyone else run into this problem? I warmed the motor for 5 minutes prior to oil removal and am positive I felt the plastic suction hose hit the bottom of the oil pan. What was I doing wrong? Thanks for your advice guys!
