Tohatsu 90 TLDI performance data

[Trevor+]

Would anyone be able to provide any performance data for this motor, or point to a web location where it is available.<br /><br />If details of the boat (weight, prop etc) and weight carried etc are avaiable that would help even more.<br /><br />I realise the data will vary for particular charistics of boat, weight carried, prop etc, however, any info (imperial or metric) would be appreciated?<br /><br />Some info presently gained from one source is: <br /><br /> 4.1kmh (2.6mph), 700rpm @ 0.7lt/h (0.2g/h)<br />40.9kmh (24.8mph), 4000rpm @ 12.8lt/h (3.4g/h)<br />58.9kmh (37.2mph), 5600rpm @ 27.6lt/h (7.3g/h)(WOT)<br /><br />Someone said that fuel consumption @4000 and 5600rpm was more than that quoted above?<br /><br />Data at 500 or 1000rpm intervals would be appreciated.<br /><br />Kind regards<br />Trevor

You can contact the distributer in your country by going to www.tohatsu.com and then going to the non-U.S. site.

Trevor, I have a 2003 90tldi on a 20' center console wooden skiff I built a few years ago. The hull weighs somewhere in the neighborhood of 900lbs. <br /><br />Speed at specific rpms are as follows:<br />1k=5mph<br />2k=7.5mph<br />3k=15.5mph<br />4k=25mph<br />5k=33mph<br />5.5k=36mph<br /><br />At a steady 4k rpms, I recorded fuel usage of 6.75 mpg. On an average trip consisting of some headway speed and some 4k cruising, I recorded 7.73 mpg.<br /><br />I have over slightly over 100 trouble free hrs on the engine now. I'm running a 13.75x15 Michingan aluminum prop.<br /><br /> http://groups.msn.com/bricog/questionablemanroofingtourney.msnw?action=ShowPhoto&PhotoID=770

The data that you are looking for can be asked for by contacting a Tohatsu distributer in your country or the one here in the U.S. To the best of my knowledge the information is not published in any public site.

Re: Tohatsu 90 TLDI performance data

Trevor<br /><br />I've owned a TLDI 90 for over 12 months now. It's on a heavy plate aluminium cuddy cab 16 ft long. I'm running the std Tohatsu alloy prop.<br /><br />The fuel economy of this motor is unbelievable, even better than I had hoped and even better than Tohatsu claim, which would have to be a first!<br /><br />I’m averaging 3.3km/litre compared to 2.25km/litre for my previous motor on the same boat, which was a 70 Yamaha. To give an example, a recent all-day fishing trip from Cleveland across Moreton Bay, through the bar and out to the 35 fathom reefs and back covered 95km and I used just 27 litres of fuel. At trolling speed it seems to use virtually no fuel at all. My last tank of fuel on a mixed run around the Bay, averaged just 6.1 l/hr. My safe working range with 100 litres under the floor has gone from about 220km out to over 330km.<br /><br />The motor starts instantly whether hot or cold, runs smoothly and there is no smoke.

I have this engine fitted to my pilot house 21' 1100kg all in back in the summer. Lovely engine.<br /><br />Our fishing club went on a trip about 24 nm out, involving long drifts in a very rough seabed area. I used about 90litres of petrol with 3 on board. On comparison, a Suzuki 70 (6 months old) used the least about 60 litres on a 16' gullwing hull boat, a Warrior 165, a deep V hull with a Mariner 60 4 stroke used about 75 litres. I would have thought the milage is pretty similar since I had the heaviest boat with the most load and mine is a 90.<br /><br />If you want here's a comparison test between various manufacturer, on 90 hp outboards.<br /><br /> http://www.bassandwalleyeboats.com/output.cfm?id=943183
