Crestliner CR 1236 2004 vs Crestliner CR 1648 M 2006 — Same Brand, Different Boat

The Crestliner CR 1236 2004 vs Crestliner CR 1648 M 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 35 hp, the Crestliner CR 1648 M 2006 has a 34-hp advantage over the Crestliner CR 1236 2004's 1-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Crestliner CR 1648 M 2006 is rated for 4 passengers, while the Crestliner CR 1236 2004 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner CR 1648 M 2006 could be the deciding factor.

Bottom line: Choose the Crestliner CR 1648 M 2006 if your priority is putting more people on the water — it handles 4 passengers and at 15,0 ft it has the deck room to back that rating up comfortably. The Crestliner CR 1236 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.

Crestliner CR 1236 2004 vs Crestliner CR 1648 M 2006 — Common Questions

Which is easier to trailer — the Crestliner CR 1236 2004 or the Crestliner CR 1648 M 2006?
For trailering, the Crestliner CR 1236 2004 has the edge at 14 lbs dry weight versus 275 lbs for the Crestliner CR 1648 M 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner CR 1648 M 2006 is rated to a maximum of 35 hp, giving it the larger power ceiling. The Crestliner CR 1236 2004 tops out at 1 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner CR 1236 2004 is Coast Guard rated for 3 passengers, while the Crestliner CR 1648 M 2006 is certified for 4. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Crestliner CR 1236 2004 measures 56" wide, compared to 7" for the Crestliner CR 1648 M 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Crestliner CR 1236 2004 and Crestliner CR 1648 M 2006 from the same manufacturer?
Yes — both the Crestliner CR 1236 2004 and the Crestliner CR 1648 M 2006 are built by Crestliner. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
