Trojan Boat Forum

Hi Folks! Here is a update from this side of the Swamp. My 10M Express has left the hard and dry for the nice and salty wet..... I launched her last Friday afternoon. She is not finished yet, but in "floatable" shape. Both engines are "purring", a new instrument panel is fitted, all new bilge pumps are in place, same as a new vacuum holding tank, new pressure water pump, and some new furniture. I had her out for a small trip yesterday, just to see her numbers in speed and RPMs. As you already know I have put in two Mercruiser Navistar 7.3 turbo diesels, both deliver 300 Hp @ 3000RPM. Props are Nibral 18 x 17, cupped. Bottom of boat is sleek as a newborn child's bum.... At 800 RPM she does 5 knots. At 1500 speed is 12-13 knots, and 2600 RPM makes her 27 knots. I will try to go the rest up to 3400 RPM, but the weather at the test time was no good, splashing and blowing. But she handles fine in the sea, steady and direct. Even if the diesels are a bit heavier than the 454s. The boat have no AC aboard, nor the genset. The fuel tank was half full, water tank and holding both empty. I am satisfied. But I still have a lot of work to do. Work like wiring for lanterns, polishing all outside, put in new sender for fuel tank, change both dynamos for two bigger (120 Amp), put in new fridges, put on new carpets in and out, and repair the teak woods. AND...if wife say yes, and my wallet also say yes, I will buy two windlasses with chain... The anchor is too heavy for lifting with arms and elbow grease.

Glad your getting her done . 2 windlasses ?

Yes, two windlasses. One in the aft, and one in the bow.

Windlass in the stern...wow. You will no doubt own the only one. Do you have a plan of attack for that addition?

Boat looks really great and at 2600 rpm, it's much faster than my '94 370 Express (19.5 mph on the gps)

Most of the boats here in Norway do have two windlasses. Mostly because they are "docking / anchor up" out on the coast, maybe in small, narrow bays, with rocks and reefs. Safety first..... I want to put the aft windlass on port side, two feet in front of aft bulkhead. I will put in a hawser /halgatt in the stern right above the swim platform and a box for the chain and rope. I will also have to put in a new battery under deck, in the same corner, to feed the windlass. And it is off course remote controlled, like the one in bow.

Here is the reason for the windlass in stern.... Very nice places to stay for the week-end. But pretty danger if the weather turns bad!

Looking great PK! Looks like beautiful boating there. Keep the pics and updates coming.

Took her out for a trip this morning. Nice weather, calm winds, and not so cold. By 3600 RPM she passed 30 knots.... And she did this every time I tried. 30.2 Knots by the Garmin GPS. In the other end (low RPM) she went 6,3 knots @ 800 RPM. I will try to fix the diesel pumps idle. 800 is way too high, should be around 500 - 550 RPM.

My home town Moss, about 45 miles south of Capitol city Oslo. Nice place in the summer time, harsh at the winter.

jealous of those numbers! we typically throw a stern anchor when were anchored for the day. dont think id be brave enough to anchor that close to those rocks!

Congrats on your diesels and those numbers.

GLAD YOU ARE OUT THERE ENJOYING HER ! ! ! !

Hi! I have fixed the idle speed today. Now both engines runs @ 500 rpm. But there is a terrible noise coming from the gearboxes. A metallic noise like a very loose tin sheet rattling around. I have checked the oil level om the boxes, that's OK. I have checked for loose elements on the engine and exhaust, turbos, gear- and throttle cables. It seems the noise are coming from something inside the boxes. Maybe I have used wrong lube oil? Dexron II. Any suggestions?

what transmissions do you have? I just had a similar issue with my velvet drive transmissions. I had my engine idle set at 500 and my trans sounded like it had a bunch of loose parts grinding around inside it, heres a link to a video

I found out that 500 was too low. I raised the rpms 700 and the sound almost completely disappeared.

PK looks like you have hurth or ZF gears , do you know what the gear number is ? 500 rpm is low for a diesel . I get a rattle if I idle mine too slow .
