Perhaps you can just modify the cover rather than remake. It's going to be a box regardless. Add some curved corners and or exterior trim pieces. You might be surprised. Looking great so far.

Hi,
Its been awhile since I have posted an update. Since last summer, not much has happened - I have the subdeck on, I have the entire Interior built out - I am waiting on the upholstry, and I have the engine rewired - this leaves a relatively short list of things to do before this summer, Including:

  • Alternator/Front of the engine
  • Throttle/shift cables
  • Rudder
  • Dashboard
  • Dashboard Wiring
  • Exhaust Tubing and Tips
  • Encapsulation of interior
  • Fuel tank & Plumbing
  • Carpet
  • Bilge Pumps & Weepholes
  • Decking
  • Chrome Fixtures

While this is a large list, once again I have cleared a three week period of my time at the end of the year at the beginning of the summer to work on the boat. Last year I was able to accomplish a considerable amount in that time; which is why I am confident in my ability to complete the boat this year. I think I should be able to get the boat running and driving at some point before the end of summer, with next years task being the fit and finish of the boat; the swim platform, wooden trim pieces, drawers & cubbyholes, mahogany floors, etc. I haven't had much time to work on the boat since I have been away at college - but I plan to continue working when I am home for breaks; I plan to get the rudder installed and encapsulate a large portion of the interior by the end of winter break. Thank you for all your wisdom and support these last few years.

-Michael

Hi guys!
Its been another year since an update has occurred. Since my last update, I have spent time in University, so I have been away from the boat for quite some time. :( But I have gotten a few small things done. I have run wires for all the accessories I can think of - and I ended up rewiring the engine yet again. I tried to clean up the engine wiring as much as I could, but the wiring harness left over from the car is quite prohibitive, so it still looks quite messy. But I have made sure each and every wire is labeled at both ends, while also grouping like items together - (starting fuses are next to starting fuses, ignition fuses next to ignition fuses, etc.) I dont believe I have shared a picture of the engine wiring before, but it is quite complicated - everything on the plywood panel attached to the side of the boat is just for the engine. I have also drilled holes for the water pickup and the rudder, and I am waiting for the epoxy to set up on those holes right now so I can do a final installation and get cracking on the cooling system. I have also fabricated some brackets to hold the behemoth of a heat exchanger. The only place to mount it was above the transmission behind the engine.

While looking at this heat exchanger, I found that running the cold raw water from the bottom then the hot raw water out the top was the easiest way to do things, but I am unsure if this is common practice. Does anybody else run from bottom to top? While progress on the boat has slowed, it most certainly has not stopped.

Thank you for your support,
-Michael

Hi Michael
I used the Toyota fuse/relay box which incorporates all those relays and wiring. Also the fuses normally used by the chassis were used for the boat's circuits. My heat exchanger is fed from the bottom. After the pickup the raw water goes through the seacock then a "T" for flushing, next through the raw water pump which is mounted beside the bellhousing and driven by a jack shaft from the front of the engine. This position is nice and compact, but a real PITA if you have to replace the impeller. Next time the engine comes out I am going to mount the pump at the front of the engine. The pump feeds the transmission cooler then up to the heat exchanger. I could not find any info on flow rates through the heat exchanger, but I had them for the transmission cooler so the raw water pump size and drive speed was designed to meet the transmission cooler's requirements. This flow rate was found to keep the heat exchanger working efficiently too. I was lucky as the 1UZ non-VVT engine has threaded mounting holes on the cylinder heads, so the heat exhanger is mounted off those. I understand the VVT heads don't have those pads. Keep up the good work.

What engine and gear is that??

Thank you Ozzieboat - I have been scratching my head about the heat exchanger for awhile. The only cost effective raw water pump configuration was crankshaft driven. I am making an aluminum "hockey puck" adapter that will fit inside the crankshaft pulley, allowing me to have a surface to mount the raw water pump to. Unfortunately to get the engine out of the car, we had to cut the wiring harness, which left the fuse box in the car. Since I have the 3uzfe engine with VVT, I believe we have different heads. There are some places on the top of the engine where I can thread bolts into, however they are oddly placed. Initially I tried to use these bolts to mount the heat exchanger, but they were too irregularly placed.
I also noticed your throttle body seems to be on the side of your engine - mine is on the front, which makes putting an air filter on it a challenge.


kens - I am using a 3uzfe mated to a zf63a - It makes about 290hp, 325 lb-ft torque, and it weighs only 430 lbs. I chose this engine because it was far cheaper, incredibly reliable (in cars), higher HP, and lower weight compared to its mercruiser counterpart.

Thanks,
-Michael

Hang in there Michael. College is very important and you will definitely benefit from it . Think of it like this. By the time you finish, you'll have a boat nearly ready to go. Even if it takes a few more years, you'll be able to enjoy it both the building and the riding. My hats off to you for doing both of these at the same time. Keep at it. You won't regret it.

Oh, is that the engine from the Toyota ski boat venture of some year ago?
What gear ratio is the ZF-63?

Yes, these engines are what Toyota used in the "Epic" boats. The one I used, as pictured, is an earlier model to Michaels. 4 litre, 260hp, 200 lbs/ft at 1000 RPM and 250 lbs/ft at 4000 RPM. 300 lbs lighter than a Chev 350. In my Monaco it consumes 12 Litres/Hr at 3000 RPM which gives a cruise speed of 30 Knots. The down side is that there is a bit of work to convert to a marine engine, although there are some "Epic" engines on the market.

I believe that the zf63 has a ratio of 1:1.5 - but I do not know for sure. I bought it for $400 off of ebay - it shifts quite nicely, doesn't leak, and was supposedly rebuilt right before I bought it. It came from a man converting his 1987 chris craft center console to diesel. Either way, I believe it was a good find.
