Engine tuning
Engine tuning
The Yamaha SVHO engine supports a wide range of engine tuning options. We have licensed the Riva SVHO tune library which includes tunes ranging from Yamaha factory stock through Low Octane (run safely with non-premium gasoline).
And of course all the higher performance tunes.
All the SVHO tunes in the Riva library are included with each of our GP1800.
Changing the ECU tune is straightforward and takes a few minutes.
Both of our GP1800 are currently configured with the Riva Stage 1 Plus tune which works well with normal 91 octane premium gasoline. This is the same octane required by the Yamaha factory tune.
Stage 1+ is an optimal tune for distance cruising and never ending smiles. Amazing acceleration, good cruise performance and eye widening top speeds.
There are higher performing SVHO tunes in the Riva library which you would have access to without additional charge.

Extended Trim control range
Longer lever arm for more degrees of Trim Up and Trim Down angle
Greater authority over hull angle in the water

More bow up for a softer ride at medium speeds on lumpy water
Trim down to compensate for passenger weight or fuel on the rear deck

The combination of aftermarket Riva intake grate for the jetpump and the extended ride plate underneath the hull takes the GP1800 up several notches.

The Riva intake grate really glues the hull to the water. You can feel it working in powered turns and overall water grip.

The extended ride plate with cut channel bottom stabilizes the rear in the water, creates extra lift to get on plane quickly and better hull tracking across the water. More precise turning with improved predictability on the water.

The ride plate can be further tuned with shims. Adjust for more speed or compensate for passenger weight.
The current configuration is optimized for a single rider with occasional passenger.
Shim changes are easy to make.

Docking cleats
Docking cleats
Super convenient to use and work really well.
One on each side, recessed to avoid snagging toes or rope.
Positioned directly below the handlebars, easy to reach.
Instantly clip on the included dock line and then secure to the dock cleat.
Much better than the Yamaha pop-up cleats, which are not offered for GP1800
Quick Attach Fenders
Quick Attach Fenders
Hook the fender bottom under the rub rail and then clip the elastic cord end into the special fender plates we have mounted fore and aft on each side just below the seat and hood. Much quicker than other methods for setting up fenders when arriving at a dock. Takes very little time.
We normally attach the fenders before getting close to the dock. Avoid boat congestion right at the dock while getting the fenders and docking line ready. Then idle in and glide to a stop at the dock, ready to lock your dock line around the dock cleat. Done.
Rear towing hoop
Rear towing hoop
Inverted J hook added to the factory tow hoop behind the rear seat.
The J hook makes it much easier and more secure to attach a tow rope or dock line.
Inverted J provides more finger access and less fiddly rope handling.
Rope disconnect is so much nicer not having to fight with tight wet knots.
Reinforced hoop plate inside the hull for secure towing.
