SeaVac Ultra specifics
What makes this one different
| Model number | RMF-120-E (RM family, boat version) |
|---|---|
| Installation | Remote mounted, piped |
| Inlet valve | Included |
| VacPort compatible | Yes |
| Dust bag | Y08 — not a Y10 or Y11 |
| Motor filter | Y21 |
| Exhaust filter | Y41 |
Two ways to pick up dirt. The SeaVac Ultra is piped, so it takes both: an inlet valve is where the hose plugs in, and a VacPort replaces the dust pan — open its door, the vacuum starts, and you sweep the dirt straight in. VacPorts · Inlet valves and fittings

Consumables
The Y08 bag is the one that seals.
The SeaVac Ultra takes the Y08-5 — five bags and one motor filter. Change the motor filter after every fifth bag, which is why one ships in every pack. Non-genuine bags and filters void the vacuum warranty.
No hose or tools aboard? That is normal. Plenty of boats get the vacuum fitted without the hose and tool kit, because the kit is sold separately. Nothing is wrong with the system — any 32 mm kit fits. Tool kits from $125.05.

SeaVac Ultra questions
Common questions
Which dust bag fits the SeaVac Ultra?
The Y08-5. It is the Y08 bag in a pack of five with a motor filter. The other SeaVac bags look similar but will not seal in this unit, so check the model number on the collar before you order.
Can the SeaVac Ultra pick up water?
No. It is a dry vacuum for cabin use only. Never use it on water, bilge water, wet sand or anything damp, and mount the power unit in a dry compartment.
Can I put a VacPort on the SeaVac Ultra?
Yes. It is a piped system, so it takes the VacPort range in LED and non-LED, plus inlet valves.
What tool kit fits the SeaVac Ultra?
Any 32 mm kit — every kit InterVac sells. The TK108-B, TK108-TB and TK108-TBM all fit, as do the individual hoses, wands and tools.
