2007 Supra Launch 21V — Low Hours, Fully Loaded, Needs Mechanical Repair

This is a fully loaded 2007 Supra Launch 21V with only 330 hours, used exclusively in fresh water. I purchased it earlier this year and have invested over $8,000 in maintenance, upgrades, and troubleshooting. Unfortunately, due to limited time and expertise, I haven’t been able to resolve one intermittent mechanical issue, and I'm now offering the boat as-is for a fast, transparent sale.

If you’ve got the skills or a good mechanic, this could be an amazing value. A ton of work has already been done.

Mechanical Overview

Engine: Indmar 325 MPI (strong compression: 185–200 psi)
Hours: 330
Location history: Single-owner boat from Seattle (before me), always stored on a lift or indoors, never used in salt water

Upgrades & Replacements ($7,000+ value)

100-hour service: impeller, oil (engine & v-drive), filters, plugs
Upgraded prop and rudder (not due to damage)
New 4-wheel disc brakes (trailer)
New dual Interstate batteries
New ballast pump
New retractable trailer straps
New winch strap
New gas shocks for storage compartments

Completed Repairs

Replaced relays (fuel pump, ignition, ECM)
Cleaned all engine grounds
ECM firmware updated and calibration re-flashed

Remaining Mechanical Issue

Symptoms: After running fine for 1–2 hours (or even just 1 minute), the engine may stumble to a rough idle and die. It will crank but not restart—until after it sits for a while.
No engine codes currently showing, and it's not going into limp mode
Mechanic suspects a fuel or electrical issue but hasn't had time to complete diagnosis
Codes that previously came up (now cleared and not returning):
- SPN 65581
- SPN 65601
- SPN 65602
- SPN 65610

What’s Included (Original Stock Components)

Triple ballast system (1200 lbs front, 1200 lbs each rear)
Hydraulic wake plate
Perfect Pass cruise control
Bluetooth stereo with head unit (currently not turning on—possibly a fuse)
Tower with:
- 4 speakers
- Board racks
- Lights

Factory covers: bow, cockpit, bimini
Custom towable cover (with tower cutouts)

Notes

Sold as-is. Serious buyers only
I’m fully transparent and happy to provide documentation of repairs, invoices, and compression test results
There are some cosmetic scratches on gelcoat from dock needing to be buffed out
A great opportunity for someone with mechanical experience or access to a trusted marine tech

If you're interested or have questions, reach out directly. Priced to move quickly for the right buyer.
