1997 Sunsetter rehab

@Bean97:  On the oil, I have used 5W-30 Mobil 1 for many years, recently went to the 0W-40 weight.  You might watch your oil pressure gauge, if it seems a bit low, particularly at idle, then at your next oil change, I would bump up the viscosity.  You will want at least 40 psi while running at speed, and it is nice to have at least 20+ psi at idle.  A good oil filter is also a good idea, my preference is the Wix 51061 which is the longer pickup truck version for the small block.  How many hours?

Thanks, Woodski.  I will have to pay attention to the oil pressure, but for some reason I remember it being higher than that at both idle and at speed.  I'll check tonight during our night ride.  I have the mobile 1 M1-302 oil filter, only because that is what my Dad last used, but am not opposed to changing.  I am running right around 650 hours.

re screws: i'd suggest moving back to brass.

if brass is over-tightened the only fret is removing the broken screw pieces and parts.

if stainless is over-tightened the pump body becomes a larger chore to repair or larger cost to replace.

Thanks, tvano!  I'll swap them out for sure, but now I know I don't need to rush.

The Mobil 1 M1-302 is the longer small block truck filter. It is high quality and is my filter of choice.

Your boat build has been a fun one to watch. Fantastic work!

@Bean97:  No issues as noted above with that oil filter, good choice, at 650 hours you should have no issues running the 5W-30 viscosity oil, and you should see many hours of trouble free use.  May simply be the oil pressure gauge, I probably should have added a +/- 10 psi tolerance on the numbers.  I kind of view the difference between idle and running (at your typical ski speed) as a rough gauge on whether the viscosity is high enough.  Engine water temperature can / will also make a significant difference.  I always warm my engine up to a point where the oil pressure won't spike high when I pull up a skier, which can be a challenge skiing in colder water.  Great work to date, have fun!

Hoping you all can help me troubleshoot an issue I have been having.  I am stating to get several spots in RPM where I am unable to keep a steady RPM or even reach some RPMs.  For example at around 2600 RPM if I give a tiny bit more throttle the RPMs jump to 3000 RPM, same thing on the way back down.  So essentially when a wakeboarder is going 15 MPH, but wants to go 16-17 MPH I cannot get them there, it is either 15 MPH or 18 MPH with no in between.  I have started noticing this at a few different places along the RPM range from 600-3200.

 

Any tips would be greatly appreciated.

Could be fuel hammer.

@Bean97 Just viewed this thread for the first time. HOLY CRAP, does that look nice. I don't even like green.

 

Nice job!!

[Woodski]

@Bean97:  Another culprit could be the throttle control, if the brass linkage joints are worn that could cause difficulty in getting a smooth or accurate throttle application.  Look at the cable to throttle control joint.  Example below:

Thanks!  Here is a picture on the water.  ~57 hours so far this summer now that my kids figured out wakeboarding and kneeboarding.

Thank you, I'll have to check if I have steel or rubber crossover lines.

Thanks, Woodski!  I will check that tonight.  Are those linkage joints right at the throttle by the driver?

back side of the morse throttle control

I just replaced my throttle cable and the brass linkage parts behind my throttle was just a little worn. Never caused a problem. 1,200 hours.

[drh]

I replaced my linkage connectors last year and they were really worn, especially the throttle one which was almost worn completely through. This really helped the controls operate smoothly.

Here's a pic; this was about 700 hours of use: https://www.amazon.com/photos/share/MJOM27aysUNJG31J8fd55qmcgDFLS6zgzlF8LUPM1ie

[coldwater-echelon]

Its funny how these little brass connectors wear.  The one on my echelon eventually broke and when I hit the throttle the boat went nowhere.

[Woodski]

@Bean97:  As noted yes backside of throttle control.  You can see from added responses, those brass parts tend to wear out and when they do wear, they twist and bind a bit.

[t229]

Where is this part located exactly.    Any pics of the location?

[DonT]

So I have the same problem with the throttle - noticed it this past week for the first time w/ perfect pass when we just bumped up our skiing speed.  Happens with both manual throttle control and perfect pass, so I believe the culprit is the fuel crossover line -  replacing this week sometime - so I'll update once I get them and have a chance to test.

[Woodski]

@DonT:  You can see it in the bottom center of the picture:  (that will be on the backside of the gunnel mounting face)

So update after I've now had a chance to test my changes by adding the new fuel crossover lines -  problem solved!

Bean,

I was having the same problem with very inconsistent RPMs, someone recommended replacing the coil. I got one on amazon for $34.04 and the boat is running smoother and faster than ever. It was so easy, 5-10 minutes to change it out tops.

I also put this stuff on my wires at my plugs and cap... https://www.amazon.com/gp/product/B016E5E59G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
