WHICH MOTOR FITS AND HOW SHOULD IT BE TRIMMED TO BOAT

below you will find information which will help you fit your outboard to your boat. its information regarding outboards and how the trim is adapatable in order to suit your boat. getting it right is the differance between better performance, efficiencty and stability in the water. getting it wrong could be dangerous and will cause you problems.

Motors

Most small powerboats, trailer-sailers and small keelboats use outboard motors.  Larger keelboats and motor cruisers will have inboards or stern drive (inboard/outboard) motors.  Whatever kind of boating you intend to do, it’s important to get a motor that’s big enough to do the job.  It’s better to have a bit more power than you need – a motor that is only just powerful enough will be working flat out all the time.  A bigger motor will cruise at less than maximum capacity, last longer, and give you some power in reserve when you need it.

Outboards

From tiny featherweight tender motors up to the huge beasts that drive Shark cats and the like, outboards like to be used regularly – long periods sitting idle aren’t good for them.  If your outboard is to be stored outside, get a cover – the elements aren’t kind to metal and paintwork.  In many areas it is important to raise the leg of the motor when leaving the boat in the water for extended periods – weed and coral growth can choke the water intake surprisingly quickly.

Never start an outboard when it is gear – as well as causing mechanical damage, there’s a high risk of loss of control.

Above about 25hp, outboards should be steered by wheel rather than tiller – the powerful torque of bigger motors makes tiller control dangerous.

Tilt and trim adjustment

To get the best performance from an outboard, you need to set it up correctly on the boat.  The location of the mounting bracket, the length of the drive shaft and the tilt of the motor all need to be positioned correctly

Boat and engine manufacturers’ recommendations should be followed carefully.

Outboard motor tilt adjustment

Incorrect:

Engine tilted too far away from stern.  Bow too high.

Incorrect:

Engine tilted too close to stern.  Bow too low.

Correct:

Hull trimmed perfect
