I was looking at an aluminum boat with a 2003 Tohatsu 40 on it & I don't know anything about these engines. Hope someone can give me an insight before I spend any money.

Check the compression BEFORE you buy it. I believe the power head is made by mercury.

Wrong and Wrong. Currently Mercury's four stroke motors up to 25hp are built in a Merc/Tohatsu joint venture factory. The only difference is the paint and the shifter mechanism. Same motors are also sold by Nissan Marine.

40hp Tohatsu's of current vintage are TLDI models.

Just as wrong:) In the U.S. Mercury's 4-strokes up through 30 hp are built by Tohatsu. Mercury also buys other 2-stroke, larger size Tohatsu's and sells them under Mercury and Mariner labels around the rest of the world. There is no joint factory as such. There is a joint venture company that owns the land, the plant on it and some production machinery. However, that plant is then leased to Tohatsu who manufacturers their engines under the Tohatsu, Nissan, Mercury and Mariner label. It is a 100% Tohatsu operation. If I remember correctly Mercury's participation amounted to a million dollars or so. It was a really done so that Brunswick could save face about who made the engines. Some of the Mercury/Mariner models have a different shift mechanism, cowling design, etc.

Hello from the UK.
I own a 2009 Mariner 20hp 4 stroke standard shaft outboard. After reading the replies on the forum I downloaded the free handbook from the Tohatsu website and the motors are almost identical. Could they both be the same engine? incidentaly the packing case had "Made in Japan" printed on it. Merry christmass and a happy new year to every one.

Which model do you have, is it a TDLI MD-40, 3 cylinder engine, a M40, 3 cylinder engine, or a 40C, 2 cylinder engine ? All, 2 strokes 40's. :D

Happy Boating
