I am kind of new to power boats having come from the blowboat world. I had always assumed that if my boat (sail boat and current Trawler style Nova) was laid over on it side it would stand back up. Is this not true? Would my Nova 36 lay over and stay there? Of course this is assuming that it...

I have seen these Planar diesel heaters on ebay that come from Russia. There are several reviews that say they have worked well in other applications (trucks and campers and such) . The price is right for a 4 Kw model @ $659 and 6 Kw @ $819. Looks similar to a Westabo or Espar but about 1/2 the...

I have twin TMD41A and they seem like well built motors. My only complaint is spare parts if I ever needed to rebuild them $$$$$$$$

In your original description you mention an over speed and rebuild. Do you think you actually getting the same power as before? Perhaps injector pump timing?...? However this would have nothing to do with the steering problem and the hot tub water.

On my boat with tmd 41As and MS4A boxes, looking from the real. starbord turns CW and port turns CCW

I own an 88 Nova 36 sundeck that may be similar. On mine there are two valves on the front bottom of the fuel tanks that allow fuel to transfer between tanks. If left open the fuel will start to go to one side, cause the boat to list and the fuel keeps going. I never leave mine open unless...

My. Volvo tmd41As have zincs in the HE and oil coolers. Perhaps that's why they are sooo reliable and every one wishes they had volvos

I don't like the idea of a break in my chain. I am sure it is approved for the strength of the chain, but I wake up at night and think about these things when the boat goes bump in the night.

2 Volvo tmd41As from 1988 with 1900 Hrs on them and they are still running strong and look good too. Poe[ple bad mouth Volvos for spares, But the more i work on mine the more i am impressed with the design and build quality.

We wanted an appartment in so cal to escape the harsh N cal winters and so the wife could paint with some artists in Laguna beach. The boat was way cheaper, faster, the rent is less, and the ocean view better the what we saw for 5X the $. The walk around queen helpped, plus lots of room for...

I think gear ratios and the motor they are attached to make a big difference in idle speed. My volvos top out at 3600 rpm and at idle of 600 i am turning my pops at 16% of their max rpm. The guy next door with the cummins that tops out at 2600 and idles at 600 is turning his props at 23% of...

The reason a diesel can run so "lean" is the it has direct injection. So at the point of injection it is not lean at all. As the spray of the injector propigates across the combustion chamber it combusts as it meets more O2 untill it is all combusted. Black smoke is created when there is too...

I also have turbo volvos tmd41a. The only issue I see with the 2000 rpm cruse is that you are probably not creating any boost. I produce some smoke until I get over 2200, I typically cruse at 2500. In one of Tony Athens articles he references an approximate 10% increase in efficiency on an...

Come on now, if you have all this brain power at your disposal someone must know about the first law of thermodynamics. Energy cannot be created or destroyed. So the plasma generator that can put out 50KW for 3 years without fuel must be using some sort of fusion or fission reaction. The...

What if the trawler had "Twin Volvos". Should be good for another 500 posts

Tony Athens provides a nice description of building in fuel tanks using FRP in the "Sunstar rebuild" article on Boatdiesel.com. Very informative and hits alot of the must have and should haves for FRP tanks. If you have not joined for the $25? you should.

The 1 to 5 min i was refering to above was the time available before the boat went down, not how long it takes to get a EPIRB signal out. My unit does have the built in GPS and the ability to be connected to my onboard GPS so the the first signal could contain my current position. It would be...

I have been pondering this exact question. The admiral has her opinions also. Lots of good points about in the ditch bag option. However i am leaning towards the have it release automatically (the coasties make rules for the commercial guys for a reason). My reasoning is for a worst case...

I have 2 TMD-41As in my Nova. There are workarounds for the oil coolers, HEs water pumps and some of the plumbing issues if you are creative. They seem to be solid engines. The bigest drawback to the 41A versions is smoking cold. They have a lower compression ratio then the newer B version...

Mine is in smugglers cove on on the SE of Santa Cruz island island in So Cal. Well a paranimeo up-loaded picture of in that location at least.

I have 1988 36 Nova sundeck with twin Volvo TMD 41A motors with about 1400 hours on them They seem like solid motors however as they say parts are hard to find. I cleaned and resealed my port heat eachanger. in the process the flange broke off the flaqnge end of the copper hard line that...

I posted about improved rudder designs a while ago. What came up was the thistle rudder design. Interesting design, google it and there is a wealth of information. What caught my attention is improved resonse for the auto pilot. it also provides better slow speed manuvering but with twin...

I dont rember exactly where i got it. Searched on the web and ordered it on-line.

Rebuilt (re-sealed) my lower helm (H50) pump sucessfully yesterday. A $30 seal kit and about 2 hours is all it takes. There are video instructions on youtube that i reviewed first. I think the bleeding the air out is the hardest part with up and down from helm station to helm station to bleed...

My 88 FHB trawler has blisters. Mine are in the 1 to several dime sized blisters per sq ft range. I had the same surveyor check out my boat that had done it for the pervoius owner 4 years earlier. They had not changed that he could notice. we left them alone for now and possibly forever...
