TM345 with hydraulic marine gearbox, gear ratio 2.47:1.<\/p>\n<p>The engine is supplied with an MPA22KBS2 engine panel with wiring harness, four KSTEUN80V rubber pads and an oil change pump.<\/p>\n<\/p>\n<p><span style=\"font-weight: bold;\">Vetus M-Line engine<\/span><br \/>is quiet, economical, reliable and has good power and torque. <br \/>The fuel system is self-detecting and the engine has an efficient charger. An additional charger is also available for the engine.<br \/><span style=\"font-weight: bold;\">Engine compartment thermal management<\/span> <br \/>The temperature in the engine compartment can easily reach 70\u00b0C. Naturally, high temperatures are detrimental both to engine performance and to other components in the engine compartment. <br \/>The water-cooled, solid cast aluminium condenser cover developed by Vetus, located on top of the engine, effectively absorbs the heat from the machine. It reduces the engine compartment temperature by up to 15\u00b0C, or up to 20%. The lower temperature improves engine performance.<br \/><span style=\"font-weight: bold;\">Sound level control<\/span><br \/>The engine running noise has a direct impact on both boating comfort and the environment. That's why we want boating to be as quiet as possible. A sturdy condenser cover combined with an efficient intake air filter housing reduces engine running noise by about 5 dBA at cruising speeds in the 2200 rpm range.<\/p>\n<p>The sound level is mostly a subjective experience but with a new model<br \/>the opinion of those who have visited the site has been consistent, \"<span style=\"font-style: italic;\">the sound level is clearly<br \/>more pleasing to the ear<\/span>\".<\/p>\n<p><span style=\"font-weight: bold;\">Improved placement of maintenance sites (see figure); <\/span><\/p>\n<ul>\n<li>relay (A)<\/li>\n<li>fuel filter and connections (B)<\/li>\n<li>wing wheel (C)<\/li>\n<li>oil stick (D)<\/li>\n<li>oil filter (E)<\/li>\n<li>on all M4 series engines except the M4.56, the raw water pump is located at the front of the engine, making impeller replacement easier in most cases.<\/li>\n<li>improved wiring harness to facilitate installation and increase safety<\/li>\n<li>electric fuel pump (F) which is activated by the ignition switch<\/li>\n<li>new intake air filter significantly reduces intake air noise (G)<\/li>\n<li>up to 26 innovations including new materials and coatings in the heat exchanger<\/li>\n<li>protective housing for V-belts for improved safety<\/li>\n<li>fixed oil change pump for easy maintenance (I)<\/li>\n<li>an aluminium condenser cover (J) which both reduces the temperature and noise in the engine compartment.<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold; color:#313184; font-size:1.2em;\">Note!
