Of course price was also very important. Trying
to compare all bids is not easy. Different engines require different
systems and cost can vary greatly. For instance some engines, though
less expensive then their counterparts, required a larger exhaust system
then we had in place. That meant additional cost in other areas. You
usually don't find this out until a mechanic has been aboard and
seen and measured your existing system.
The mechanic we had selected was not the least expensive, but also not
the most money. In addition this mechanic was the only one that gave
a FIRM price. That is, if there was more than that outlined in the original
bid he said he would not charge more. That impressed us.
Of course every boat is different and no two will cost the same to repower.
Still I thought someone may be interested in what we spent. It was $85,000.00
for everything. As you can see this is not something to be taken lightly
however in our case we figure we saved about $100,000 when compared to
replacing our boat with another used vessel.
It's not
just a re-power! - There are lots of other items that must be considered
when replacing engines aboard a boat. This is especially true when going
way up in horsepower as we did. We were removing twin 200 HP engines
and replacing them with 370 HP engines. That meant a lot of systems needed
to be made larger or stronger. Fortunately our boats basic structure
could handle larger motors so no major structural reinforcing work was
required. Even so a lot of changes were needed. |
| Here is what we had done
and what was included in our price. |
- Old engine removal.
- Two New Cummins 370hp B Diamond Series Engines.
- Two New ZF transmissions.
- New engine mounts.
- New stronger propeller shafts (same diameter /
better material).
- New larger Nibral props.
- New "dripless" shaft packing systems.
- Side venting of exhausts and punching out the
mufflers to relieve exhaust pressure.
- We had the entire engine room painted and refurbished
while the engines were out.
- We completely replaced the fuel system with new
larger lines and a new fuel/water-separating filter system.
- We had to put in larger raw water intakes.
- We had to put in larger raw water strainers and
all new hoses.
- New sets of engine gauges for both the upper and
lower stations.
- New bottom paint
- New raw water through hull and seacock for a future
bait tank. (figured we might as well while the boat was out of the
water)
- 2 months of Boat Yard storage including removing
and replacing boat in water.
- Replacement of the 12-Volt system from the battery
boxes up to the electrical panel.
- A new custom battery box.
- Tax
