396 Motor Yacht

[KyleR]

Keeping the rpms at 1050 I have been able to repeatedly reproduce 2.5mpg and 3gph results. This equates to about 8mph with no current and covers 5000ish miles traveled and 800ish engine hours. But don't forget to run the engines up and get some load on them each run to keep from getting carbon/oil buildup.

Thank you! that is much better than I thought

After some back and forth we have signed and placed a deposit on the boat. Next step is the survey. Hopefully it will go well.

KeysGuy - welcome!!! I have had a 396 for 4 or 5 years now and its the best boat I've owned! Same engines, 6BTA are bulletproof engines! Here are some of the things I would look at:

Aft Shower. Check for soft wood at the bottom under the glass door. I believe I did a string on my repair. I'll shoot it over if I can find it.

Here is a chart I made for mine, seems to work pretty good. My speeds are a shed lower than book speeds but otherwise it works well. Let me know if you want the excel spreadsheet I used to make this and you can adjust it as you feel the need. Not sure I can share that kind of stuff via this forum.

650 Guy,

Thank you very much! Lots of good information. I'll let the surveyor know to look at that area. the 8th is the day. BTW I grew up in Vermilion and graduated from HS there. For 4 years 1986-1990 worked for South Point Marine Towing out of Huron. Fall of 1990 I moved to Key West and I've been in the Lower Keys ever since.

Nice! We just left the Keys a few weeks ago. We spent most of the winter there cruising all around after doing the "Florida Loop". We made it out as far as Boca Grande but could never get a weather window to make it to the Dry Tortugas....so that will have to wait until next year!
